This book presents Wireless sensor networks (WSNs) refer to networks of spatially dispersed and dedicated sensors that monitor and record the physical conditions of the environment and forward the collected data to a central location. WSNs can measure environmental conditions such as temperature, sound, pollution levels, humidity and wind.

It is an outcome of expensive research carried over many years towards addressing energy problems in wireless sensor network. With the increasing inclination towards adoption of wireless sensor network, the research community consistently struggles for overcoming energy problems within the sensor node. After reviewing enough research articles, I found that problems towards energy-efficient routing is still unsolved and no robust or benchmarked technique or algorithm exists that can take this claim. I have studied this problem and developed a very novel framework for ensuring enhanced network lifetime in sensor network.
