This book will develop the management skills in the field of Computer Network. That is the optimization resource usage with minimal input. The book contains the mainly on Wireless Sensor Networks (WSNs) as widely considered as one of the most important technologies for the twenty-first century. WSNs employ thousands of small sensors that communicate between themselves in a distributed manner using Medium Access Control (MAC) protocols. Energy required for wireless sensor is obtained from non-rechargeable energy sources. Due to their small size, wireless sensors are highly constrained in terms...
