Current military wireless sensor networks, such as Optical Acoustic SATCOM Integrated Sensor (OASIS) from Textron Systems, are composed of mini sensors that have the ability to sense phenomena from the surrounding environment and communicate the gathered data to a base unit where the information is sent via satellite to a command and control unit. These systems have limited coverage, require carefully planned deployments and have a single point of failure. New wireless sensor networks are composed of sensors that collaborate in performing sensing tasks and improve detection and tracking performance through multiple observations, geometric diversity, extended detection range and faster response time. These sensors form an ad hoc network to deliver aggregate information from geographically diverse areas to their destinations. The sensors act as relays and can be randomly deployed, allowing for extended coverage. Data routing in sensor networks has the main function of establishing and maintaining paths through which this data is transmitted from their sources to their destinations. In this report, we explore the design issues of data routing protocols in wireless sensor networks. Our main goal is to establish a solid starting point for research on routing protocols for military mission-critical wireless sensor networks. As such, we first discuss the characteristics of sensor networks in order to extract some requirements on the operation of routing protocols within these networ
