Efficient Routing Protocols and Coverage Issues in Wsn

Wireless sensor network is the most favorable topic in the current era, as the technology is growing tremendously the size of the devices are decreasing gradually and hence the sensors are getting smaller and inexpensive. This makes the deployment of wireless sensor network less complicated, but not only size of the sensor is the problem other different issues are also there like coverage and connectivity issues, without proper coverage of the monitoring area and isolated sensor nodes will never form a proper network. There are different routing protocols which are prominent for the evolution of the wireless sensor network. In this survey we are going to discuss these coverage and connectivity issue and different routing protocols, so that it can help in future research work
