Simulation of ad hoc network / Zaheera Zainal Abidin

Ad hoc network is an instantaneous or spontaneous network which can be achieved without the network infrastructure provided to end user. In IEEE 802.11 LAN, the independent basic service set typically a minimum of two nodes. Nodes are able to communicate directly and usually in the form of pre-plann...
