Sensor network is the real time network defined under application specific and environment specific constraints. The restricted node level and network level constraints increase its complexities. The network is composed under architectural specifications. While forming the communication and gaining the optimization, it is required to consider the associated issues. These issues provide the setting up constraints and communication decision at earlier stage so that the preventive network level and environment level adjustments can be done. In this paper, some of the sensor network issues are presented and discussed.
