Mobile ad-hoc networks (MANET) are particularly vulnerable on account of its intrinsic characteristics of open medium, dynamic topology, absence of central authorities, distributed cooperation and constrained capability. These vulnerabilities create significant challenges for routing protocols operating in the entire network. In which, the reactive routing, i.e. AODV, bears the brunt of various kinds...
In this paper, we discuss some possible deployment patterns of wireless sensors to achieve both coverage and connectivity which were ignored in the discussion of "Deploying Wireless Sensors To Achieve Both Coverage And Connectivity, ACM, MobiHoc, 2006", and we prove that the strip-based patterns are absolutely optimal among all the deployment patterns of wireless sensors to achieve both...
In this paper, we propose an efficient privacy-preserving scheme for secure packet transmission at wireless link layer. The proposed scheme is constructed by using hash values in reverse hash chains as interface identifiers. It can successfully and efficiently resist the Media Access Control (MAC) address based attacks, such as flow tracking and traffic analysis, which are launched by either outside...
Due to the nature of wireless ad hoc networks such as dynamic infrastructure and non-centralized management, the routing process has a huge exposure to malicious hacking and intrusions. This fact results in a likelihood of node compromise, leading to a disruption of the legitimate network functions/services. Most reported studies in coping with the problem have focused on the effort of protection...
