Topology issues should receive more and more consideration in Wireless Sensor Networks (WSN). While the supplied underlying network topology typically optimizes WSN applications, another inclination is observed to optimize WSN employing topology control. In the current ten years, wireless sensor network technology has speedy development. After a concise prologue of the wireless sensor network, some main protocols of WSN are provided. Then the comparison is made between the various protocols with advantages and disadvantages. | A review on the performance of different routing protocols in WSN - A comparative survey
