Machine to machine (M2M) communication, which is also known as machine type communication (MTC), is one of the most fascinating parts of mobile communication technology and also an important practical application of the Internet of Things. The main objective of this type of communication, is handling massive heterogeneous devices with low network overheads and high security guarantees. Hence, v...

We propose a bandwidth-efficient algorithmic solution for perfectly-secure communication in the absence of secure infrastructure. Our solution involves connecting vertex pairs by a set of k edge-disjoint paths (a structure we call a k-system) where k is a parameter determined by the connectivity of the network. This structure is resilient to adversaries with bounded eavesdropping capability. To...

there are more than 750 counties in 13 provinces and autonomous regionsconstituting 30% of china lands which are facing serious problem of desertification. theseareas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part ofnortheast china, north central china and most of northwest china. biological methods are theultimate way for drift sand stabilization and a fu...

Many mobile applications in wireless networks such as military battlefield, emergency response, mobile commerce, online gaming, and collaborative work are based on the notion of group communications. Designing security protocols for secure group communications in wireless networks faces many technical challenges due to unique characteristics of wireless networks including resource-constrained e...

Secure communication in ad hoc networks is an inherent problem because of the distributiveness of the nodes and the reliance on cooperation between the nodes. All the nodes in such networks rely and trust other nodes for forwarding packets because of their limitation in the range of transmission. Due to the absence of any central administrative node, verification of authenticity of nodes is ver...

In this position paper, we address some current limitations and challenges as well as emerging directions in three related areas of secure communication: (1) security in Wireless Sensor Networks – WSNs, (2) security in Mobile Ad Hoc Networks – MANETs, and, (3) security in Cellular Phone Networks.

The Egyptian Eastern Desert, the part of Sahara Desert that connects Nile and Red Sea, is rich in natural resources meshed with multiple networks. adoption camel as main mode transportation 1st millennium BC, faster a greater load capacity than humans or donkeys, dramatically changed logistics used to cross this difficult terrain. Our objective, therefore, understand reconstruct circulation reg...
