Abstract: Sensor networks are increasingly being deployed, either randomly or manually, for monitoring of physical environments subjected to different applications such as medical, military, agriculture, industry, transport etc. One of the most important applications of a wireless sensor network is critical conditions monitoring. In cases like critical condition monitoring application, it is important that information can be sensed from the physical environment, where the sensor network is deployed, while the emergency state is in progress. For critical conditions such as fire, leaking of toxic gases and explosions, the system must be fast enough to respond for foreseen events (targets) with in a fraction of seconds. A great challenge to these networks is to provide a fast, reliable, and fault tolerant channel for events diffusion even in the presence of emergency conditions that can lead to node failures and path disruption, like dust, fire etc, to the sink that receives those events. The main aim of this thesis work is to discuss in detail and evaluate the performance of different routing protocols selected from wireless sensor network (WSN) and mobile ad hoc network (MANET) for critical conditions monitoring applications with the help of important metrics. The result shows that multi-path and multi-speed (MMSPEED) routing protocol has a very good performance of events delivery with in a short end-to-end delay and high ratio of packet delivery by creating a reliable path for packets reaching to the destination in case of critical conditions monitoring applications with the limitation of moderate power dissipation when compared to other routing protocols.
