A mobile ad hoc network MANET is a self-organized wireless network where mobile nodes can communicate with each other without the use of any existing network infrastructure or centralized administration. Trust establishment and management are essential for any security framework of MANETs. However, traditional solutions to key management through accessing(More)
Securing wireless mobile ad hoc networks (MANETs) is challenging due to the lack of centralized authority and poor connectivity. A key distribution mechanism is central to any public key management scheme. We propose a novel key distribution scheme for MANETs that exploits the routing infrastructure to effectively chain peer nodes together. Keying material(More)
This contribution presents a proposal of an applicable routing messages protocol (RMP) which uses nodes location information and a multi-hop forwarding scheme to achieve long-range communication in Wireless Sensor Network Grids (WSNG). Ant Colony (ACO) accumulative technique has been applied to collect the hops list in the message way toward the sink. The(More)
