Abstract:
Cluster based protocols like LEACH were found
best suited for routing in wireless sensor networks. In mobility
centric environments some improvements were suggested in the
basic scheme. LEACH-Mobile is one such protocol. The basic
LEACH protocol is improved in the mobile scenario by ensuring
whether a sensor node is able to communicate with its cluster
head. Since all the nodes, including cluster head is moving it will
be better to elect a node as cluster head which is having less
mobility related to its neighbours. In this paper, LEACH-Mobile
protocol has been enhanced based on a mobility metric
“remoteness” for cluster head election. This ensures high success
rate in data transfer between the cluster head and the collector
nodes even though nodes are moving. We have simulated and
compared our LEACH-Mobile-Enhanced protocol with LEACHMobile.
Results show that inclusion of neighbouring node
information improves the routing protocol.
