Modified distributed energy-efficient cluster for heterogeneous wireless sensor networks

Abstract

A wireless sensor network consists of inexpensive power constrained sensors which collect data from the environment and transmit them towards the base station in a cooperative way. Reducing the energy and extending the wireless sensor networks lifetime, imposes a great confront. In this paper, the distributed Energy efficient clustering protocol was used to calculate the energy efficiency of the network. Existing DEEC was modified and developed a new protocol called MDEEC. MDEEC allows more number of data to be sent from the base station to the cluster head in a particular time interval. Compared to DEEC, MDEEC performs less delay for sending the data, thereby increasing the energy efficiency of the heterogeneous network.
