Performance evaluation of Wireless Mesh Network routing protocol for smart grid networks

Recent Advances in Wireless Mesh Networks (WMN) makes it one of the candidate communication technologies for Smart Grid Automatic Metering Infrastructure (AMI) because of its scalability and low cost of deployment. However, its capacity and multi-hoping performance in dynamic environment may not guarantee resilience and packet delivery reliability requirements of AMI. Theoretical and practical studies have shown that the multi-hoping capacity of a mesh network is constrained by increase in the number of nodes and number of hops in the network. In addition traffic requirements for smart meters will further compound WMN multi-hopping issues. In this paper, the performance of WMN when deployed for AMI is carried out using two wireless routing protocols; Hybrid Wireless Mesh Protocol (HWMP) and Optimised Link State Rout protocol (OLSR) in NS-3. Simulation results show that compared to the reliability requirement of AMI, there is need for improving the routing metric for both protocols. Furthermore, The Dynamic Link Exchange Protocol (DLEP) which allows layer 2 link estimation was proposed to enhance the route decision

How to Choose the Relevant MAC Protocol for Wireless Smart Parking Urban Networks?

Parking sensor network is rapidly deploying around the world and is regarded as one of the first implemented urban services in smart cities. To provide the best network performance, the MAC protocol shall be adaptive enough in order to satisfy the traffic intensity and variation of parking sensors. In this paper, we study the heavy-tailed parking and vacant time models from SmartSantander, and then we apply the traffic model in the simulation with four different kinds of MAC protocols, that is, contention-based, schedule-based and two hybrid versions of them. The result shows that the packet interarrival time is no longer heavy-tailed while collecting a group of parking sensors, and then choosing an appropriate MAC protocol highly depends on the network configuration. Also, the information delay is bounded by traffic and MAC parameters which are important criteria while the timely message is required.Comment: The 11th ACM International Symposium on Performance Evaluation of Wireless Ad Hoc, Sensor, and Ubiquitous Networks (2014
