Executive Summary

In wireless sensor networks and ad hoc networks, energy uses are in many cases the most important constraint since it corresponds directly to operational lifetime. It's due to their remoteness; it makes inability to resupply power to these energy-constrained devices. Therefore to extend a wireless sensor network's effectiveness, the lifetime of the network must be increased by making them as energy efficient as possible. An energy-efficient Medium Access Control (MAC) and routing protocol can maximize the whole network lifetime. This paper focuses on a protocol stack solution that deals with MAC layer and Network layer, which minimizes the energy consumption and delay required to transmit packets across the network.
