In a Wireless Sensor Network (WSN), low powered and low cost sensors/nodes are collaborated with each other to communicate. Since the sensors are battery powered, it utilizes the limited resources such as memory, energy, etc. The issues that affect WSN are localization, energy, synchronization, QoS, security, etc. In this paper, the authors consider certain issues such as localization, energy, communication overhead and connectivity. The localization and energy efficiency are optimized by the algorithm, FIXPOS. Similarly, the connectivity and communication are dealt with DPCB algorithm, which reduces communication overhead and increases area of coverage.
