Sensor networks are recently rapidly growing research area in wireless communications and distributed network. Sensor network is a densely deployed wireless network of small, low-cost sensors, which can be used in various applications like - health, environmental monitoring, military, home, gathering and sensing information in inhospitable locations etc. Wireless sensor networks monitor and control physical environments from remote locations. Sensor nodes suffer various energy and computational constraints for their low cost feature and ad hoc deployment method. Different application areas of sensor networks consist different technical issues and researchers are currently shedding their lights to resolving these issues. The prominent deficiencies are: energy efficient routing, protocols, localization algorithms and system design.
