Abstract Wireless sensor networks (WSN) are gaining more potential from research community due to the large spectrum of their applications. Energy efficiency is one of the most important aspects of WSNs. This thesis proposes a new medium access control (MAC) protocol for WSNs called E²MAC which focuses on energy efficiency enhancement. E²MAC focuses mainly on decreasing the time WSN node needs to stay awake for idle listening with minimal impact on throughput and packet delay by using, among other features, duty cycle fashion of sleep/active pattern of operation with dynamic active time that extend or shorten in run time based the traffic load |
