An Extension of MAC Protocol for Mobility Detection and Efficient Data Transmission
In this paper, the authors introduce an extension of MAC protocol for mobility detection of nodes and efficient data transmission in mobile, multihop wireless sensor network. Here for mobility detection, receiving power of the node is consider by the transmitting node. If gradual degradation in communication link does due to degradation in receiving power, it initiates the switchover of link via the relay node for efficient data transmission. Their present implementation is done by extending the energy efficient IEEE 802.11 MAC protocol because most commonly used standard is IEEE 802.11 in sensor networks consist of small, inexpensive, resource constrained devices that communicate wirelessly in a multihop network.
