This paper deals with the retransmission protocol design for cognitive radio networks by exploiting the primary hybrid ARQ. In contrast with previous work that focuses on cancellation based retransmissions, we propose a novel cooperative coding based retransmission protocol for cognitive radio networks. The design objective is to improve the throughput of the primary user and create the transmission...
Recently, the cooperative communication has been explored more and more as an impressing technique to combat the effects of channel fading and to reduce the energy consumption in wireless networks. However, the impact of cooperative communications on transmission rate has not been well-addressed yet. In this paper, we provide an analytical framework for transmission rate enhancement issue in wireless...
This paper addresses the secure data aggregation for wireless sensor networks (WSNs) with both static tree architecture and dynamic cluster-based architecture. For WSNs with static tree architecture, we propose the Leaf Node Representation (LNR) scheme to solve the Id problem and make the key stream-based encrypted data aggregation feasible and practical for large scale networks. For WSNs with dynamic...
This paper provides and describes a method of on-vehicle detection system of hybrid electric vehicle (HEV). Some functions like data detection, analysis, process and the control of hybrid electric model can be implemented based on LCD and touch screen interface. The designed system is not limited on normal processes of vehicle parameters such as speed, miles, rotation speed of engine, voltage and...
This paper constructs an energy efficient secure data aggregation framework for wireless networks, especially for wireless sensor networks with femtocells. We propose the Leaf Node Representation (LNR) scheme and the Hop-by-hop MAC Authentication (HMA) scheme, in order to provide a balance between the security and the communication cost. The ideas in this paper are not restricted to wireless sensor...
