Effect of forwarding strategy on the life time of multi-hop multi-sink sensor networks

Abstract

Lifetime of a sensor network can be extended by judicious energy expenditure. Energy consumed is primarily a function of inter-nodal distance and thus effect of forwarding technique can no longer be overlooked while trying to enhance the lifetime of sensor network. Lifetime of a network has been defined differently in different papers depending upon the nature and application of the sensor network under consideration. In this paper we have proposed a forwarding scheme and have compared the same with greedy forwarding and residual energy based forwarding while finding the lifetime for the sensor network. © 2013 Springer Science+Business Media New York.
