A medium access control protocol to provide efficient mobility in wireless sensor networks
The aim of this research is to enhance the media access control (MAC) protocol for mobile sensor networks based on the standard IEEE 802.15.4 so that it can overcome the synchronisation, association and collision problems due to the movement of the nodes.
The current standard only supports static wireless sensor networks and the protocol is believed to degrade the network performance if it is applied in mobile sensor networks.
The main objective of this research is to make sure that the enhanced protocol maintains the throughput and consumes minimum energy when operates in mobile sensor networks environment. The synchronisation, reassociation and association problems will be improved by making the node aware of its position whether it is moving away or towards to its original co-ordinator.
