Markovian model analysis for energy harvesting nodes in a modified opportunistic routing protocol

摘要

Opportunistic routing protocol with cross-layer design mainly focuses on energy-harvesting principles and is named as modified energy-harvesting opportunistic routing protocol (MEHOR). In the cross-layer design, we follow the Markovian model where the parameters are exchanged between the different layers in order to optimise the usage of energy. MEHOR focuses on energy constraints at a sensor node because it requires recharge, once its energy level gets depleted. Basically, we put emphasis on regioning in order to overcome the multi-path routing problems, especially the energy availability. We minimise retransmission rate (12%), cost optimisation and reduce collision (8%) considering data packets received in a linear multi-hop energy-harvesting wireless sensor network (EH-WSN). Finally, we compare MEHOR with other advanced routing protocols like opportunistic routing (OR) and energy-harvesting opportunistic routing (EHOR).
