Abstract: A wireless sensor network (WSN) is the network of large number of sensor nodes that connect to each other with or without help of existing infrastructure. A WSN base station is a huge database and receives data from sensor nodes. Each sensor node performs tasks of sensing, processing, data communication and can be de ployed in locations which are di cult for humans to access. WSN systems can be broadly categorized as either static networks or mobile/ dynamic networks. Static sensor network involves setting up a network where the sensor nodes are arranged in xed positions. Dynamic or Mobile WSNs (MWSNs) contain mobile nodes and are suitable for applications involving obtaining information from moving objects such as animals or humans where sensor nodes need to be attached directly to objects and move with them. MWSNs can be used for habitat monitoring, health-care, en vironmental monitoring, transportation networks, underwater surveillance, military applications and many more. A routing protocol helps to nd the path from sensor node to the sink. Routing in MWSNs has several challenges as against static sensor networks due to dynamic conditions. Energy is the most constrained resource as the sensor nodes are battery operated and preferably used in remote environments. The major contribution of the thesis is proposition of two new routing protocols namely Connectivity Based Energy E fficient Opportunistic Robust (CBEEOR) rout ing and Connectivity-based Cross-layer Opportunistic Forwarding (CCOF) for rout ing in MWSNs and an approach for predicting the network lifetime based on residual energy of node . Both the protocols use a neighbour node list prioritized on the basis of expected cost of forwarding the packet called as prioritized forwarder list. Conclu sions of the research work are crisply, pointing towards the possible areas of future research in this eld. In CBEEOR, expected cost of forwarding is determined as combination of packet transmission cost, expected packet relaying cost and network connectivity cost
