	abstract = {Our aim with this paper is to introduce a new protocol for self-organization and data-collection in heterogeneous wireless sensor networks (WSNs) called SDCP (Self-organization and Data-collection Protocol). This protocol is supported by two types of special mobile nodes (SƿN) that are rich in resources (those that can move by flying (such as Unmanned Aerial Vehicle - UAVs) and those that can move on the ground (Actors)). Through our SDCP protocol, we plan to ensure optimal performance measures, such as energy efficiency, low latency, high success rate, a moderate number of hops, and suitably interactions between static sensors and SpNs while benefiting from their mobility (in a hierarchical heterogeneous network with unstable architecture due to mobility). The SƿN moves conforming to a particular mobility model, namely random waypoint mobility model, which allows pause time. Each SƿN, while it is suspended, forms a transitory cluster that heads for collecting and processing sensed data (sensed by static sensor nodes in that cluster). During his trip, SƿN piggybacks the collected data and returns it to a base station (BS). Once the data transferred to the BS, SƿN continues its movement again for a new data collection. The simulations carried out, delighted us with valuable performance outcomes.},

	The main purpose for wireless sensor networks is especially for data collection. Nevertheless, since the sensors are mostly immobile, the operation of transferring data they captured to the base station is a critical task since the exchange environment is unstable. Our approach consists in injecting mobile relay nodes whose mission is mainly to maximize the lifetime of the network, also to provide connectivity between any sensor and the base station, and to minimize the latency of receiving data sent to the base station. Smart mobility is the key for our approach to ensure reliability by forming a virtual mobile circle using relay nodes. We have proved formally and by simulation the effectiveness of our approach, the obtained results prove the efficiency of our approach.

	abstract = {Mobile Heterogeneous Wireless Sensor Networks (Heterogeneous WSNs) are mainly characterized by their internal diversity. In such networks, the variety of properties in each component provides profitable outcomes related to many metrics such as network lifetime and hardware cost. Although it offers remarkable advantages, random mobility causes major difficulties in the management of Heterogeneous WSNs. The purpose of this paper is to introduce a controlled mobility approach for Heterogeneous WSNs using Unmanned Aerial Vehicles (UAVs). According to experiments, the proposed deterministic and genetic methods can efficiently deal with the complexity of Mobile Heterogeneous WSNs compared to the previously applied random strategies. The obtained results prove that our suggested techniques can achieve a greater delivery ratio, a faster coverage time, and a faster latency.},

	abstract = {Mobile Wireless Sensor and Actor Networks (MWSANs) can simply be defined as an extension of Wireless Sensor and Actor Networks (WSANs) in which the actor nodes are mobile. As such, in addition to challenges existing in WSAN, the mobility also imposes new challenges such as localization of actors, cooperative tracking of both actor-actor and actor-sensor collaboration, and communication infrastructure between distant actors. New communication protocols, specific to MWSANs, are needed. In this paper, we propose a self-organization and data collection protocol in order to provide energy efficiency, low latency, high success rate and suitably interactions between sensors and actors and take benefit from the mobility and resources existing on the network{\textquoteright}s actor nodes. The actor nodes move according to RWP mobility model. Each actor, during its pause time creates a temporary cluster, and is the head of it, collects and processes sensor data and performs actions on the environment based on the information gathered from sensor nodes in its cluster. Once an actor detects a base station it delivers the collected data to it. The simulations carried out (with TOSSIM tool), comfort us with good performances results.},

	Mobility has always represented a complicated phenomenon in the network routing process. This complexity is mainly facilitated in the way that ensures reliable connections for efficient orientation of data. Many years ago, different studies were initiated basing on routing protocols dedicated to static environments in order to adapt them to the mobile environment. In the present work, we have a different vision of mobility that has many advantages due to its {\textquoteright}mobile{\textquoteright} principle. Indeed, instead of searching to prevent mobility and testing for example to immobilize momentarily a mobile environment to provide routing task, we will exploit this mobility to improve routing. Based on that, we carried out a set of works to achieve this objective.

For our first contribution, we found that the best way to make use of this mobility is to follow a mobility model. Many models have been proposed in the literature and employed as a data source in most studies. After a careful study, we focused on the Random Waypoint mobility model (RWP) in order to ensure routing in wireless networks. Our contribution involves a Random Waypoint model (in its basic version) that was achieved on the TOSSIM simulator, and it was considered as a platform for our second (and main) contribution, in which we suggested an approach based RWP where network nodes can collaborate and work together basing on our recommended algorithm. Such an approach offers many advantages to ensure routing in a dynamic environment. Finally, our contributions comprise innovative ideas for suggesting other solutions that will improve them.},

	Many solutions have been developed for routinginformation in ad hoc networks. However, few of them are effectivewhen the topology is very dynamic. Indeed, building a routing table,finding and maintaining a path or location of a node is a bigchallenge when mobility is high. Currently this topic attracts theattention of several research groups including those interested inthe vehicle networks (VANET), a special case of dynamic networks.The VANET will improve road safety and develop new services todrivers or passengers, such as access to Internet for example. Inthis paper, we present a new approach for routing in very dynamicnetworks based on communication conditions.
