Hybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design

Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. To establish a secure communication, two nodes must share common key from their key-rings. Otherwise, they can find a key- path in which ens...

Performance of a Novel Hybrid ARQ Scheme for Trellis Coded Modulation in Wireless Networks

A novel trellis-coded modulation-based hybrid ARQ scheme which provides multiple levels of error correction is proposed in this paper for efficient and reliable data transmission. The analytical throughput bounds of the proposed scheme are derived and verified by simulations. Numerical results demonstrate that an improved throughput is achieved by the proposed scheme over other recently propose...

Hybrid Coupling Scheme for UMTS and Wireless LAN Interworking

We propose a hybrid coupling scheme to connect UMTS and WLAN networks. Under the tightcoupled system, users of WLAN can also use the services of UMTS with guaranteed QoS and seamless mobility, but it is a problem that the capacity of UMTS core network nodes is not enough to accommodate the bulky data traffic from WLAN, since the core network nodes are designed to handle circuit voice calls or s...
