Abstract: The topology of the Mobile Ad hoc Networks (MANET) is altered frequently due to the nodes mobility. It also affects the path of transferring data from the member nodes to the sink. In this study, the sink is considered as mobile to collect the information from the member nodes. Initially the sink node is assigned with a current speed and direction. At each fixed intervals of time, the speed and direction of the sink is updated. The Mobility supported Energy aware Medium Access Control (MEMAC) protocol is implemented with IEEE 802.11 MAC to identify the direction and speed of the sink. The relay node is one of member nodes and is chosen based on the movement of sink node. The parameters like direction of mobility of sink, distance between sink to member, RSSI and residual energy of member node are utilized to find the relay node in the domain. The extensive simulation implemented with NS2 event driven simulator to validate the performance of the MEMAC algorithm. The experimental results shows that the MEMAC outperforms well compared to the previously stated algorithms in terms of relay node selection, path stability, data collection and throughput.
