Performance Analysis of Mobile Ad Hoc Networks Security | Ad hoc, Performance, Security

Ad hoc networks have a great importance in modern scientific and technological usage. Ad hoc network does not need a topology,infrastructure and special management. Security limits its functionality specially in unsecured environment. This work comes to solve this problem by modifying one of the used protocols in ad hoc networks, which is Ad Hoc On-demand Distance Victor(AODV) routing protocol that depends on finding route path just when need to. This modification has done by using some reserved bits from Route Request(RREQ) packet to add security feature by selecting encryption algorithm to protect payload data that is transferred between nodes of communication by considering workload level at each node when selecting route path. In addition, this work presents a technique for distributing public key to be used within RSA algorithm by adding a new part to RREQ packet. The performance of the standard and modified AODV protocol also studied in this work by considering some parameters that affect ad hoc network performance, which are mobility and number of nodes while communication process.
