Abstract

Challenging issue in Wireless Sensor Networks (WSNs) is assessment of
energy and lifetime at different nodes within the networks. Various methods may be
employed to improve lifetime (reduce energy consumption). One such method involves
balancing loads on nodes when data is being transmitted from source to destination
nodes. Multi-path routing techniques can be used for this purpose. In these techniques
no global information is available regard the path, making it difficult to create multipath
routes from sources nodes to destination nodes. Another problem with these
networks is a routing applied to source nodes independently from that applied used
for destination nodes. This creates energy loss and reduces lifetime. To overcome
this problem, the present paper makes use of clustering by selecting virtual nodes
to gather information from sources and sending it to destination nodes. The New
Protocol for Enhancing Nods Lifetime (PENL) is implemented through NS-2.
