TBEE: Tier Based Energy Efficient Protocol Providing Sink and Source Mobility in Wireless Sensor Networks

In resource constrained Wireless Sensor Networks (WSNs) it is important to utilize energy efficiently. Data dissemination is mainly responsible for the consumption of energy in Sensor Nodes (SNs). The data dissemination protocols for WSNs should reduce the energy consumption of the SNs. Sink and source mobility is the major challenge for data dissemination protocols. In this paper, a Tier Based Energy Efficient protocol (TBEE) providing sink and source mobility in WSNs has been proposed. TBEE protocol has been designed so that fewer SNs located nearer to the Dissemination Point (DP) respond to the sinks message for grid formation thereby reducing message overheads.
