-The Wireless Mesh Network (WMN) is a multi-hop wireless network consisting of mesh routers and clients, where the mesh routers have minimal mobility and form the backbone. The WMN is primarily designed to access outer network to mesh clients through backhaul gateways. As traffic converges on the gateways, traffic hotspots are likely to form in the neighborhood of the gateways. In this paper, we propose Congestion Aware Multi-path Routing (CAMR) protocol to tackle this problem. Upon congestion, CAMR divides the clients under a mesh STA into two groups and returns a different path for each group. The CAMR protocol triggers multi-path routing in such a manner that the packet reordering problem is avoided. Through simulations, we show that CAMR improves the performance of the WMN in terms of throughput, delay and packet drop ratio.

“…Due to the requirements of variable application traffic, a number of improvements and modification have been carried out in HWMP to support these applications in Smart Grid [6,13]. They include: i) modifying the route selection mechanism to reduce route fluctuations, ii) local route recovery mechanism by using alternative routes, iii) calculation method of the air cost metric that considers Smart grid's data characteristics, and iv) a mechanism to tackle the ARP broadcast storm problem in 802.11s-based NANs by piggybacking the MAC address resolution in the proactive rote request of HWMP.…”

“…Nonetheless, modifications of these protocols and other routing protocols are still being carried out to suit Smart Grid's application traffic characteristics. For example, performance evaluation and reliability improvement of HWMP (IEEE 802.11s standard) was carried out for Smart grid in [6] and [7] which resolves the original problems of HWMP. Given that HWMP works at the MAC layer, it is worth exploring and modifying other protocols that work at the network layer.…”

Abstract-Recent advances in ad hoc Wireless Mesh Networks (WMN) has posited it as a strong candidate in Smart Grid's Neighbourhood Area Network (NAN) for Advanced Metering Infrastructure (AMI). However, its abysmal capacity and poor multi-hoping performance in harsh dynamic environment will require an improvement to its protocol stacks in order for it to effectively support the variable requirements of application traffic in Smart Grid. This paper presents a classification of Smart Grid traffics and examines the performance of HWMP (which is the default routing protocol of the IEEE 802.11s standard) with the Optimised Link State Routing (OLSR) protocol in a NAN based ad hoc WMN. Results from simulations in ns-3 show that HWMP does not outperform OLSR. This indicates that cross layer modifications can be developed in OLSR protocol to address the routing challenges in a NAN based ad hoc WMN.

“…1 presents a structure of the multiple metric-OLSR protocol for NAN in AMI. The node architecture is a modification of HWMP-RE proposed in [11] and CLQM proposed by [12] which defines interfaces between the application and network layer. It is expected to create a platform that will enable evaluation of link parameters and the calculation of paths to NAN destination using multiple link metrics in order to guarantee QoS routing for different targeted application.…”

“…In contrast, when routing traffic applications that are latency tolerant or loss sensitive (LS) as in power quality measurement traffic, a metric that has the best delivery reliability performance should be the first priority. The loss sensitive and delay sensitive AMI traffic were represented by power quality traffic transmitting a packet size of 3000 bytes every 3 s and Wide Area Measurement (WAM) traffic transmitting a packet size of 48 bytes every 0.1 s respectively [11]. …”
