Abstract: 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%.
