In this paper, we study the delay-constrained information coverage problem in mobile wireless networks. Motivated by real application needs, our formulation takes advantage of the node mobility for information collection, which takes place when a node moves into the proximity of stationary base stations. To the best of our knowledge, we present the first formulation for the delay-constrained information...
In this paper we address the issue of store-carry and forward (SCF) relaying within a cell in a mobile network. The proposed scheme can be considered as a generalization of various multihop wireless relaying schemes, where storing and carrying an information message by a mobile relay node is not allowed. The key motivation of utilizing SCF relaying within the cell is that energy consumption levels...
This paper proposes an efficient authentication scheme, which is suitable for low-power mobile devices. It uses an elliptic-curve-eryptosystem based trust delegation mechanism to generate a delegation passcode for mobile station authentication, and it can effectively defend all known attacks to mobile networks including the denial-of-service attack. Moreover, the mobile station only needs to receive...
