In the region of mobile wireless sensor network, getting least energy consumption is a very important research problem. A number of energy proficient protocols have been implemented for static wsn, generally built on a layered design approach, i.e. they are motivated on designing ideal strategies for “single” layer by considering the sensor nodes as static. In proposed paper, we consider a cross-layer design. A new MAC protocol termed MAC-SWITCH is proposed. In this new approach, the communication between MAC and routing layers are fully exploited to achieve energy efficiency for various paradigms of mobile wireless sensor networks. More surely, in the proposed MAC-SWITCH algorithm, routing and data information at the network layer is used by the MAC layer such that it can reduces number of contention for channel and perform protocol switching based upon type of data. The performance of the proposed MAC-SWITCH is evaluated by quantification and simulation. The quantification is done by using gauss lattice point theorem and simulation by using the NS-2 simulator. It has been evident that the proposed MAC-SWITCH outperforms the existing aloha and SMAC protocols in terms of energy efficiency, number of contention, packet transmission and network lifetime.
