Abstract
Intrusion is something which is unsolicited activity and which might be used to interrupt the functions of wireless network. If we talk about wireless networks, having centralized monitoring policy; therefore it is very much easy to detect and eliminate intrusions efficiently. But when we look forward to wireless scenario, especially in the multi hop wireless network, intrusion activities are more because of the lack of centralized monitoring policy. Wireless network is very much vulnerable to different kinds of attacks and intrusions at different OSI layer due to mainly co-operation among their noses. Intrusion detection is the most fundamental component of defense in depth strategy, are capable to identify security attacks and raise an alarm to inform authorities. Intrusion detection system, a passive defense strategy informs about attacks to network administrator because the attacks come easy to wireless network. Intrusion detection system is a second line of defense. Lots of IDSs are proposed in the literature, capable to detect attacks in a particular layer of the OSI model. Here we are proposing Cross layer IDSs, which is capable to detect multiple layer possible attacks.

Summary
Infrastructure-less WMN is a kind of peer-to-peer or ad hoc networks among client device in which thereWireless Mesh Network (WMN) has primarily two types of architectures such as infrastructure-based and infrastructure-less WMN (Khan et al, 2008a). Infrastructure-less WMN is a kind of peer-to-peer or ad hoc networks among client device in which there. Infrastructure-based network has mesh clients, mesh routers and fixed and wired Mesh gateway. Mesh routers form the infrastructure for clients in Multi hop fashion and it is very easy to implement and extend. Infrastructure-less network router is not necessary because nodes have routing capability between sources to destination. In this case highest level communication occurs. The reason is that infrastructure-less WMNs have many design constraints such as low energy, low bandwidth, limited processing, memory constraints and are highly vulnerable to many security attach such as passive, active and Denial of Service (DoS) (Khan et al, 2008b). Infrastructure-based WMS supports both is said to be secure, if it ensure all time availability, static and mobile nodes
