Book excerpt: Recent work in designing of routing protocols in wireless sensor networks has progressed in an interesting direction, namely energy efficient protocol for a common objective of prolonging the network lifetime. However, there is a lack of research on policy-adaptive aspects to manage the network from the application point of view. We introduce a tentative yet pertinent solution in two directions. First, we proposed an energy-aware protocol to make the energy balanced in the network without generating "hot-spot" areas which leads to longer network lifetime because the node survives longer. Second, we designed a policy-adaptive framework with reactive (on-demand) routing by adopting policy restraints of applications in making routing choices. We validated our protocol using NS2 simulation tool and have shown that the protocol indeed balances energy and builds an effective routing schema with policy-adaptive routing while extending the lifetime of the whole network.
