Abstract: “Mobile Adhoc Network (MANET) is a network without any infrastructure and no central authority. Absence of central authority makes MANET more vulnerable to various security attacks. MANET uses one of the address allocation schemes for configuration of new node. Address allocation schemes have several threats e.g. Address space exhaustion attack, IP spoofing, Address conflict threat, Address spoofing threat, etc. This paper suggests a novel approach that uses routing table based solution to detect address space exhaustion attack. Our solution uses three fields of routing table: destination address, hop count, hop limit. An ensuring mechanism is suggested in this paper to ensure detection of address space exhaustion in the network.”

Keywords: MANET, Address space exhaustion attack, malicious node.
