In this paper, we propose a preamble-based medium access control (P-MAC) mechanism in Ad-Hoc network. Different from traditional carrier sense multiple (CSMA) network, P-MAC uses much shorter preamble to establish the First, shorten time of establishing Based on P-MAC, more efficient way maintain Next, focusing power line communication (PLC) network which is kind frequency division (FD-PLC) arc...

Ad hoc networks provide a low-latency, high bandwidth, and dynamically reconfigurable network infrastructure that can disclose the full potential of the network to the user. Use of Jini technology in an ad hoc environment allows the user to enter a network and become a user of services without apriori knowledge of the existence of the network or its services. However, Jini lacks security provis...

Mobile Ad-hoc network (MANET) has become an individual part for communication for mobile device. Therefore, interest in research of Mobile Ad-hoc network has been growing since last few years. Due to the open medium, dynamic network topology, autonomous terminal, lack of centralized monitoring and lack of management point Mobile Ad-hoc network are highly vulnerable to security attacks compared ...
