In Wireless Sensor Network (WSN), the data delivery models, such as periodic, event-driven, have implications on the overall network topology. In this paper, a distributed event-aware topology management scheme, for WSN, is proposed. The proposed scheme, named as Event-Aware Topology Management (EATM), periodically constructs the network topology on the basis of the current event state, and the state of the nodes of the network. EATM partitions the network into clusters, and uses concepts intertwined with the concepts of Facility Location Theory, in a distributed manner, for reducing the energy dissipation of the event monitoring nodes by reducing their average transmission distance. Simulation results show that EATM can reduce the average transmission distance of event monitoring nodes by 30 % over LEACH and HEED. It is also shown that EATM is able to conserve 15 % energy of event-monitoring nodes and enhances the network lifetime by at least 5 % time.
