Multipath routing is an efficient technique to route data in wireless sensor networks (WSNs)
because it can provide reliability, security and load balance, which are especially critical in …

A main design challenge in the area of sensor networks is energy efficiency to prolong the
network operable lifetime. Since most of the energy is spent for radio communication, an …

A wide range of applications in wireless sensor networks rely on the location information of
the sensing nodes. However, traditional localization techniques are dependent on hardware …

This paper deals with early obstacles recognition in wireless sensor networks under various
traffic patterns. In the presence of obstacles, the efficiency of routing algorithms is increased …

Résumé La résolution du problème des vides dans le routage géographique dédié aux
réseaux de capteurs sans fil (RCSF), rencontrés lors de la remontée des informations vers …

Objectives: To review the basic principles of Multi-path Routing Protocols (MRPs) design
and its performance metrics. To discuss the assortment of MRPs overview for Wireless …

Open voids are often formed on the boundary of a deployed wireless sensor network (WSN).
Geographical routing protocols must handle these voids where packets fall into local …

The presence of obstructing obstacles severely degrades the efficiency of routing protocols
in MANETs. To mitigate the effect of these obstructing obstacles, routing in MANETs is …

In this paper, we propose a novel routing protocol called the Cartography Enhanced OLSR
(CE-OLSR) for multi hop mobile ad hoc networks (multi hop MANETs). CE-OLSR is based …

We study the problem of routing messages in sensor networks where the energy saving
issue is essential. In this paper, we propose ROAM2, an improvement of ROAM (Routing …
