Increasing Sensor Network Lifetime by Identifying and Leveraging Nodes with Excess Energy In Heterogeneous Networks

We propose and evaluate wireless sensor routing algorithms designed to extend the lifetime of a heterogeneous wireless sensor network. The network is heterogeneous in the sensors’ energy distribution and also in the amount of data each sensor must communicate. As a basis for comparison, we analyze the lifetime of a network using a simple, nearest-neighbor routing algorithm and an analytic solution to the optimal lifetime of networks meeting certain constraints. We compare the performance of all the routing algorithms in simulation.
