Performance Optimization of Network Protocols for IEEE 802.11s-based Smart Grid Communications

Abstract

The tunneling mechanisms in the LTE network cause a downlink traffic problem to IEEE 802.11s. For the network interoperability, at the network layer of EPC network, a novel UE access list was proposed to address this issue. At the datalink layer, to handle QoS mismatch between IEEE 802.11s and LTE network, Dual Queues approach was proposed for the Enhanced Distributed Channel Access. The effectiveness of all proposed approaches was validated through extensive simulation experiments using a network simulator. The simulation results showed that the proposed approaches outperformed the traditional TCP/IP protocols in terms of end to end delay, packet delivery ratio, throughput, and collection time.

Improving the Reliability of Optimised Link State Routing in a Smart Grid Neighbour Area Network based Wireless Mesh Network Using Multiple Metrics

“…It extends the IEEE 802.11 standard by adding self-forming multi-hop mesh networking capability into the MAC layer of the IEEE 802.11. The IEEE 802.11s also incorporates routing at the MAC layer and uses the IEEE 802.11e [10] MAC enhancement for QoS support. IEEE 802.11s uses the hybrid wireless mesh protocol (HWMP) as a default routing protocol; however, ad hoc link state routed protocols, such as OLSR, may also be supported [10].…”

Although the IEEE 802.11s was approved in 2012, it is still being investigated to identify potential performance and QoS issues in large networks, such as NAN.…”
