Battery allocation for wireless sensor network lifetime maximization under cost constraints
Wireless sensor networks hold the potential to open new domains to distributed data acquisition. However, such networks are prone to premature failure because some nodes deplete their batteries more rapidly than others due to workload variations, non-uniform communication, and heterogenous hardware. Many-to-one traffic patterns are common in sensor networks, further increasing node power consumption heterogeneity. Most previous sensor network lifetime enhancement techniques focused on balancing power distribution, based on the assumption of uniform battery capacity allocation among homogeneous nodes. This paper gives a formulation and solution to the costconstrained lifetime-aware battery allocation problem for sensor networks with arbitrary topologies and heterogeneous power distributions. An integer nonlinear programming formulation is given. Based on an energy
