Communication over the network where the nodes are disconnected and continuously moving is highly challenging; mainly because the probability of an end-to-end network connectivity or stable infrastructure is negligible or almost zero. Spatial Networks, Military Networks, intermittently connected Wireless/Mobile ad-hoc networks, etc. are some examples of such networks. With the advancement of technology and application requirements, the need for communication over these types of networks is increasing. Delay Tolerant Network is an emerging area of networks that target at providing a solution here. Communication over DTN involves forwarding through intermediate nodes that store, carry and forwards the message in an opportunistic way. This store and forward scheme arise many security challenges; most of the security mechanisms available today are irrelevant or cannot be applied in DTN environment. Moreover, DTN based implementations require hardware or software modifications to be applied in existing systems or schemes. Thus, in all, limiting DTN based solutions in the real world. Aiming to address communication over challenged, isolated, damaged or broken networks, this paper proposes, WI- FI Assisted Communication Network (WACN), a communication network of mobile challenged networks that uses DTN based store and forward scheme on the default Wi-Fi capability. The proposed network communicates securely and without depending on any conventional methods, i.e. independent of infrastructure, service provider, internet connectivity etc.
