A wireless network it's based on ad-hoc wireless networks, where each node transfers data to the neighbor nodes. AP (Access Point) need not be in the reach of all the nodes in the network. Nodes around the AP forward the packets from the distant nodes to the next node. They can work in a decentralized fashion, are cheap with minimum investment for initial infrastructure, more reliable, scalable and provide increased coverage. The Denial of Service attacks (DoS) have become more and more frequent and caused some fatal problems in the recent time.
