In a Wireless Sensor Network (WSN), routing is the process of finding a
cost effective route in terms of power consumption. As an evaluation
criterion for the WSN performance, network lifetime is directly affected by
the routing method. In a wide variety of WSNs, different techniques are used
as routing methods, such as shortest distance path. In this paper, we
propose a novel algorithm, optimizing power consumption in WSN nodes, based
on the shortest path algorithm. In this approach, the energy level of nodes
and their geographical distance from each other contribute to the weight of
the connecting path. The proposed algorithm is used as a data dissemination
method in WSNs with randomly scattered nodes. We also apply Dijkstra?s
shortest path algorithm to the same networks. The results showed that the
proposed algorithm increases the network lifetime up to 30 % by preventing
nodes with low charge levels from early disconnection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
