Abstract: Security for network services is a prevalent requirement against fraudulent access to the conveniences in WMN. A secure communication is indispensable for stopping the unauthorized access to the network services in wireless technology. A number of researchers have proposed various security schemes but most of them are vulnerable against several performance metrics i.e. security threats (black hole and grey hole attack), low packet delivery ratio (PDR), increased packet loss ratio (PLR) and reduced throughput. A secure routing protocol is needed in order to get rid of such precincts. In previous paper, Secured Authentication and Signature Routing (SASR) protocol proposed a secure signature routing protocol which provides the communication using Diffie Hellman and threshold signature. In this manuscript, SASR is enhanced with AV-SASR (Advanced Version of SASR) by modifying AODV (MAODV) protocol which is robust against black hole and grey hole attack. Further network metrics are measured in terms of PDR, PLR and throughput in comparison of SAODV and SEAODV. The analysis is done over both the scenarios i.e. with the involvement of malicious node and without involvement of malicious nodes.
