Abstract Details

2003, MS, University of Cincinnati, Engineering : Computer Science.
Most sensor network applications demand that the network have a long operational lifetime.This requires that energy efficient routing schemes be used while routing sensor data.In traditional routing schemes some nodes are utilized considerably more than the other nodes, which results in these energy constrained nodes becoming bottlenecks, thereby reducing the operational lifetime of the network. In this work we propose a Multipath routing protocol to avoid the creation of these bottleneck nodes. This protocol deterministically distributes the routing load on all nodes in the query region thereby creating a more stable and balanced network where all the nodes are at similar energy levels. Our simulations have shown a significant improvement in the operational lifetime of the sensor network. These networks are expected to find wide applicability and increasing deployment in coming years, as they enable reliable monitoring and analysis of the environment. Users of such a system will expect to get a real time warning when time-critical situations occur in the network and also to be able to retrieve any required information by issuing queries to the network. Our scheme classifies available paths based on their route length, so that time critical queries could be routed through low latency paths. We exploit the knowledge of the nature of queries to determine which path would be most suitable for fulfilling the application specific requirements. The routes assigned to non-critical query traffic are dynamically adapted at run time to balance the excess load generated by the critical queries along minimum delay routes.
