Energy Efficient Real-Time Services for Wireless Sensor Networks with IEEE 802.15.4

A Wireless Sensor Network (WSN) distinguishes from other wireless or wired networks through its capability of interaction with the environment. Such networks have been used under various applications including life safety, disaster relief, smart environments and industrial monitoring systems, which require a large amount of wireless sensors which are battery-powered and are generally designed for long-term deployments with no human intervention. Consequently, energy efficiency and reliability is the main design objectives for these sensor networks. Since reliability is highly application-dependent, it is possible to trade-off energy consumption and reliability in order to prolong the network lifetime and also satisfying the application requirements (QoS).
