Alternative Abstract
Wireless sensor networking is an emerging technology that has a wide range of potential applications including monitoring, medical systems and robotic exploration. Sensor networks normally consist of a large number of densely deployed distributed nodes that organize themselves into multiple-hop wireless networks. As sensor networks become an integral component of future communication services, energy efficiency will be an important design consideration due to limited battery life of sensor nodes. Since the communication component is a significant consumer of energy, considerable research has been devoted to low-power design of the entire networks protocol stack of sensor networks. This thesis proposed four different energy efficient schemes for sensor networks. First one is topology generation algorithm by using flooding and gossiping methods with some new parameters. In second scheme, we proposed energy efficient algorithm to help routing protocols to increases a network lifetime by fairly distributing the relay load among the nodes with the help of two different operating modes. We proposed an IS-MAC protocol in third scheme that improves the energy efficiency further from S-MAC and T-MAC by redefining the minimum timer period. We also addressed the QoS issues like per-node fairness, channel capacity utilization and latency. Finally IS-MAC based flooding protocol is presented in fourth scheme. All the performance evaluation for each scheme shows that proposed schemes save the energy consumption over existing schemes in given sensor networks.
