Mobile Adhoc network is an on the fly network with a dynamic topology where the node association changes frequently. Such a network is vulnerable to different types of attacks as there is no centralized mechanism for providing the security and due to the fact that the network uses 802.11 based MAC layer which is considered to be a very weak in terms of security and data integrity. Packet injection is one of the most severe attack types in such a network. A Packet injection is type of attack where by any unauthenticated node injects malicious packets along with the valid data or control packet. Detection of such injections are difficult and requires huge processing which drains limited battery resources of MANET. Therefore in this paper we propose a unique technique for minimizing packet injection attack with the help of traffic splitting and fair resource reservation policy for the neighbors. The method is compared with conventional cryptosystem based transmission and it is shown that the performance of the proposed system is way better in preserving network lifetime while ensuring better protection against packet injection attacks.
