Abstract
RPL is the routing protocol for low-power and lossy networks and has recently been considered as the standard routing protocol for IPv6 based low power personal area networks using the IEEE 802.15.4 protocol. RPL is oriented towards supporting multi-point to point communications. RPL aims to minimize the cost to reach the sink node from any node in the network. However, RPL lacks a load balancing mechanism to maximize the lifetime of the battery-powered wireless sensor networks by preventing overloaded nodes from being drained quickly. In this thesis, we propose the minimum degree RPL (MD-RPL) which builds a minimum degree spanning tree to enable load balancing in RPL. Extensive simulations were carried out to evaluate the proposed scheme using the COOJA simulator. Our MD-RPL results in up to 15.6% improvement in the maximum power consumed and 65% in the variance in the average consumed power
