Maintaining security associations (SA) in mobile ad hoc networks (MANET) is challenging due to their intrinsically open, dynamic, and decentralized nature. Bandwidth limitations arising from both the physical characteristics of the wireless medium and the control overhead required to maintain routes in a network with changing topology add another level of difficulty to the problem. While establishing...
Secure routing is the milestone in mobile ad hoc networks. Ad hoc networks are widely used in military and other scientific areas with nodes which can move arbitrarily and connect to any nodes at will, it is impossible for Ad hoc network to own a fixed infrastructure. It also has a certain number of characteristics which make the security difficult. Routing is always the most significant part for...
A mobile ad-hoc network (MANET) is a peer-to-peer wireless network where nodes can communicate with each other without the use of infrastructure such as access points or base stations. Nodes can join and leave the network at anytime and are free to move randomly and organize themselves arbitrarily. Due to this nature of MANET, it is possible that there could be some malicious and selfish nodes that...
The MIDAS project has developed a middleware platform for context aware MANET services. A key problem with MANETs is the lack of a central authority and pre-existing trust. Thus it is hard to enable a trusted environment where context can be verified and trusted by peers. This paper describes how the MIDAS middleware can become "secure enough" for typical applications by identifying which...
