Lifetime Maximization of Heterogeneous Wireless AdHoc Networks
In this paper, we address the problem of energy
efficient routing in homogeneous and heterogeneous wireless ad
hoc networks aiming at maximize the network lifetime. We
define the network lifetime as the number of transmissions
the node can perform until the first node fails due to battery
exhaustion. In static networks we find a routing (spanning)
tree which maximizes the network lifetime without tree update.
We have proposed a Global weighted incremental power model
and Global weighted post sweep for extending the life time of
heterogeneous wireless ad hoc wireless network that gives better
performance than the WBIP(Weighted Broadcast Incremental
Protocol) implementation. We consider the amount of energy the
node has compared to the maximum energy in network as the
parameter in the cost metric function for constructing a efficient
routing tre
