The conventional power grid has several drawbacks and a new powerful Smart Grid perspective has been recently introduced. The Smart Grid principle, allowing to efficiently manage an electrical grid network, needs to exploit a Communication network for interconnecting the Smart Grid devices. An increasing interest is toward wireless communications due to their higher flexibility. Within this context Cognitive Radio (CR) techniques has been introduced aiming to exploit more efficiently the radio spectrum resources.
In Neighborhood Area Network (NAN), mesh grids can be considered as one of possible network topologies. In such networks, no Base Station is required and Data will be sent to the gateway by means of nodes themselves. Hence, routing is one of the main issues in such networks.
Routing in such networks should be done by a protocol which maximizes throughput against Cognitive Radio drawbacks, reduces delay and would be stable under traffic load. CORPL has been introduced as a routing protocol to meet some of these goals.
In this dissertation, CORPL routing protocol will be evaluated under traffic load and it’s throughput and delay will be improved by means of a multigate scheme. Then after changing scenario to a case which simultaneous receiving and sending of packets are possible, a novel routing multigate protocol for smart meters data in smart grids will be proposed, it’s stability region will be determined, stability would be proved in this region and its functionality from point of delay and throughput will be evaluated.
