Wireless networks have recently gained a lot of attention from the research community. Wireless Mesh Network (WMN) and Wireless Sensor Network (WSN) are characterized as multi-hop wireless networks. WMN is an integrated broadband wireless network which provides high bandwidth internet service to user; whereas WSN is an application oriented and generally set up for gathering records from insecure environments Security has been a long trade off with Wi-Fi. Early wireless networks heavily leaned on WMNs to provide Layer 3 security, which kept aside from the additional overhead of encapsulation and challenges of roaming, Quality of Service, client support and scalability and left the IP network vulnerable to attacks. In the deployment of sensor nodes in an insecure environment makes the networks vulnerable to a variety of potential attacks, the inherent power and memory limitations of sensor nodes makes conventional security solutions unfeasible. There are several limitations and vulnerable features of WMN and WSN, along with the associated security threats and possible defenses. Security requirements for wireless networks are confidentiality, data integrity, data authentication and service availability.
