Wireless Sensor Network (WSN) was originally used by military applications such as battlefield surveillance. Though, now it finds application in many industrial and civilian application areas also. The WSN primarily consist of spatially distributed autonomous devices that make use of sensors to cooperatively monitor physical or environmental conditions. Grid computing is another technology that facilitates resource sharing. This is a type of distributed computing environment where disparate resources such as computer CPUs, storage, applications and data are utilized through virtualization and collective management. Using sensor grid, the upcoming computing paradigm, one can enhance the grid computing paradigm to the next level where sharing of sensor resources and data from wireless sensor networks in a grid network is made possible. This is sure to change the way we interact with the physical world. Still, there is a long way to go and many challenges need to be taken care of. One of these challenges is Quality of Service management. Addressing this problem, this document attempts to design a Quality of Service (QoS) aware sensor grid communication protocol. For this, the paper explores grid network, wireless sensor network and sensor grid network communication. The paper also takes up the various issues and challenges that would come in the way of designing a QoS-aware communication protocol for sensor grid.
