Distributed and Reliable Leader Election Framework for Wireless Sensor Network (DRLEF)

The leader election mechanism plays a central role in all technologies requiring automation since the apparition of distributed systems. Indeed, the leader ensures coordination, tasks affectation and charge distribution between the network nodes. Many approaches are proposed in the literature for electing the leader, they commonly present a set of limitations such as the need to go through a spanning tree building stage with the presence of a risk of one point to failure and so on. In this article we present a new distributed algorithm called DRLEF (Distributed and Reliable Leader Election Framework). DRLEF makes use of local information only, it lists the direct neighbors, allows the mapping of the leaders by region and prepares candidates who replace them in case of a failure. The obtained simulation results are very promising.
