Future wireless cellular systems, i.e., high-speed downlink packet access (HSDPA) and 1x EVolution Data Optimized Revision A (1xEV-DO Rev A), promise to revolutionize the mobile users' wireless experience by offering high data rates that are beyond the capabilities of third-generation (3G) systems. These systems, however, require proficient radio resource management schemes to provide the high data...
Secure time synchronization is one of the key concerns for some sophisticated sensor network applications. Most existing time synchronization protocols are affected by almost all attacks. In this paper we consider heterogeneous sensor networks (HSNs) as a model for our proposed novel time synchronization protocol based on pairing and identity based cryptography (IBC). This is the first approach for...
Key management is a key concern for security operation in sensor network. Most existing key management schemes try to establish shared keys for all pairs of neighbor sensors, no matter whether these nodes communicate with each other or not, and causes large overhead. In this paper, we propose a novel key agreement protocol based on pairing-based cryptography. The proposed protocol reduces the key...
Key management poses a main concern for security operation in sensor network. Most existing key management schemes try to establish shared keys for all pairs of neighbor sensors, no matter whether these nodes communicate with each other or not, and causes large overhead. Recent trend of research mainly consider homogeneous sensor network and a few consider heterogeneous sensor network for key management...
