Abstract

In this master thesis, the LATOR protocol was developed as a routing proposal for Wireless Body Area Networks (WBAN). LATOR aims to increase the Package Delivery Rate (PDR) in intra-WBAN communication and to prevent node overheating. LATOR considers the selection of routes based on the link quality information and prevents overheating by controlling node activity. The proposal was implemented and evaluated using the Castalia framework. Experimental results show that LATOR allows a better performance in the packet delivery rate when the direct communication is of low quality and there is some other alternative route with better quality. At the same time, overheating of the nodes in the network is avoided, maintaining an adequate PDR performance. LATOR slightly increases end-to-end latency; nevertheless, it is considered a viable alternative for WBAN applications.
