The frequent failures in Wireless Mesh Networks (WMNs) cause severe performance degradations during their lifetime. This increases the need of re-routing of links in WMNs. Expensive manual network management is required for their real-time recovery. This paper presents a Streamlined Re-routing Algorithm (SRA) that enables a multi-radio WMN to autonomously recover from local link failures to preserve...
This paper provides an analysis of optimum offered load that maximizes the throughput of IEEE 802.11 media access control (MAC) protocol for the multihop network. We extend Ping Chung Ng analysis in presence of hidden terminal and capture effect, with some modifications in the derivation of throughput. The analytical throughput results are validated against ns-2 simulation using direct sequence spread...
This paper presents an analytical model and the performance study of IEEE 802.11 distributed coordination function (DCF) for the nonsaturated heterogeneous traffic. In this paper, we modify the Bianchipsilas Markov chain model for the nonsaturated environment and analyze the throughput under several conditions and several set of parameters, with the aim of obtaining the accurate throughput when stations...
This paper presents an analytical model for the performance study of IEEE 802.11 distributed coordination function (DCF). The maximum throughput can be achieved well below the saturated load. The analytical model for finite load must be studied to know the performance of the medium access control (MAC) layer below the saturated load. We extend the Bianchipsilas saturation model for the nonsaturated...
