Over the past few decades, wireless mesh network is the main area of research in small and large sized network structure. Wireless mesh network is a radio based network scheme that needs minimal structure and organisation. It has the capability to integrate the wired system and can be prolonged at minimum cost without losing the mobile nature. Routing protocols mainly affects the performance of the WMN. Some of the advantages of the WMN are cost effective, easy management, robust and reliable service. It is utilised in numerous application areas such as hospitality and healthcare applications, rescue actions and disaster controlling, broadband connection services at home and institutions. In WMN , some challenges faced are, unsuitable number of alternate routes among the pair of the hops, entire capacity decreased due to interference among the multiple connections, effect on security due to complex networks. In a wireless mesh network, described about the optimized link state routing protocol (OLSR) and works on network parameters. In routing protocol, an immediate routing is required so that the change in topology may lead to flooding of data to desirable hosts in the system. After that, routing, performance is evaluated with encryption method using DES. Data encryption standard (DES) is cryptographic method that is applied to block of information. In this research proposed work, developed a novel improved, optimised link state routing method to enhance the network performance end to delay, delivery rate and recover the loss of data from sender to receiver hop. Experimental analysis is done using various parameters metrices as end delay, packet delivery ratio and throughput. In this research, an improvement in discovery delay of PASER and FER is also increased. The frame error rate computed is based on the level ranges range from 0%, 10% and 20%. Moreover, packet delivery ratio is 70% and throughput is 81%.

Two folded work presents channel allocation scheme sustaining channel orthogonality and channel spacing to reduce CCI (Co-Channel Interference) and ACI (Adjacent Channel Interference) for inter flow of an intra-flow link. Proposed scheme as a part of radio resource allocation is applied on infrastructure based backhaul of wireless mesh network using directional antennas. The proposed approach is applied separately on 2.4 and 5GHz bands. Interference of connectivity graph is modelled by strongly connected directed graph and greedy algorithms are used for channel allocation. We have used OPNET Modeller suite to simulate network models for this research. The proposed arrangement reduces the channel interference and increases system throughput. In this research, the influence of channel is computed in terms of network throughput and delay.

“…Moreover, dynamic channel assignment requires high speed synchronization. Due to challenging issues for achieving dynamic channel assignment, static channel assignment has been proposed [9][10][11][12]. In [9], the authors propose an end-to-end channel allocation scheme (EECAS) that extends the radio-frequency-slot method to minimize co-channel interference.…”

In procedure of computing the k node-disjoint paths (line [8][9][10][11][12][13][14][15][16][17][18][19][20], our algorithm is different from the max-flow algorithm. Specifically, we use the shortest path or Prim's minimum spanning tree algorithm to find an augment path between two nodes.…”

SUMMARYIn multi-radio multi-channel wireless mesh networks, the design of logical topology is different from that in single channel wireless mesh networks. The same channel assignment algorithm used for various logical topologies will lead to diverse network performance. In this paper, we study the relationship between k-connected logical topology and the maximum number of assigned channels. Meanwhile, we analyze the issues affecting channel assignment performance, and present the lower and upper bounds of the maximum allowable number of assigned channels for k-connected logical topology. We then develop a k-connected logical topology design algorithm based on shortest disjoint paths and minimum interference disjoint paths for each node-pair. In addition, we propose a static channel assignment algorithm according to minimum spanning tree search. Extensive simulations show that our proposed algorithm achieves higher throughput and lower end-to-end delay than fault tolerant topology control algorithms, which validates the involved trade-off between path length and nodal interference. Moreover, numerical results demonstrate that our proposed channel assignment further improves network performance under the context of limited radio interfaces.
