Abstract: Clusterbased routing protocols are better than other routing protocols for wireless sensor networks in terms of network topology management, energy minimization as well as data aggregation. In this paper, a novel protocol EAHEED (EnergyAware Hybrid EnergyEfficient Distributed) is presented to solve the problems including huge energy waste, short network age and application difficulty. An improved clustering generation algorithm is put forth to improve the efficiency of the cluster head generation algorithm, in which a routing tree is established on the cluster head by time sharing multiplex. A clustering head routing tree is designed, which reduces the network energy through improving the clustering parameters for cluster head election.The simulation results show that EAHEED can prolong the lifetime of wireless sensor networks further compared with the LEACH and HEED protocols.
