Abstract
Wireless mobile adhoc network (MANET) is a dynamic network. Nodes in a MANET have high degree of mobility from one domain to another in a particular time interval. In such a dynamic network, security is a major concern. In this paper, the authors propose an inter domain agent based secure authorization and communication for mobile clients/nodes (MCs) in MANET. Mobile agents (MAs) are software programs that support the mobility of clients in different domain and provide necessary resources to the clients for safe execution. It also shares the key with MCs in different domains. An algorithm for secure authorization and communication between MCs having mobility in different domains is proposed. The scheme is evaluated on ns-2 w.r.t. metrics such as overall cost in terms of overhead generated, admission and traceability cost, and itinerary chosen by MAs w.r.t. mobility of MCs.
