Implementing Energy Efficiency in Wireless Sensor Network

Objective/Aim

One of the most significant issues in wireless sensor networking is power consumption. Although new hardware devices have larger energy sources and tend to consume less power, it is important that network protocols and software are aware of power consumption. The goal is to control the hardware resources in a way that minimizes power usage while still providing constant or near-constant network availability.
The wireless sensor network interface is one of the largest sources of power consumption in a network device. This is counter to the general usage pattern of wireless sensor devices, where network access is often intermittent. Wireless devices tend to spend a great deal of their time in a network-idle state. One way of addressing this problem is to turn off or put to sleep those network interfaces that are idle for an extended period of time.
