Distributed Velocity-Dependent Protocol for Multihop Cellular Sensor Networks

A Cross Layer Routing Protocol for Multihop Cellular Networks

We propose a cross-layer routing protocol for a Code Division Multiple Access (CDMA) Multihop Cellular Network (MCN). In designing the routing protocol for MCN, multiple constraints are imposed on intermediate relay node selection and end-to-end path selection. The constraints on relay nodes include willingness for cooperation, sufficient neighbourhood connectivity and the level of interference...

Power Allocation based Hybrid Multihop Relaying Protocol for Sensor Networks

In this paper, Hybrid relay systems are comprised of Amplify-andForward (AF), Decode-and-Forward (DF) and DeModulate-and-Forward (DMF) together in cooperative networks. We propose adaptive relay schemes based on Channel State Information (CSI) of the received Signal-to-Noise Ratio (SNR) at the Relay Node (RN). We select the relay protocol adaptively, on the basis of Power Allocation (PA) constr...

HYREP: A Hybrid Low-Power Protocol for Wireless Sensor Networks

In this paper, a new hybrid routing protocol is presented for low power Wireless Sensor Networks (WSNs). The new system uses an integrated piezoelectric energy harvester to increase the network lifetime. Power dissipation is one of the most important factors affecting lifetime of a WSN. An innovative cluster head selection technique using Cuckoo optimization algorithm has been used in the desig...

Protocol Considerations for Distributed Sensor Networks

Hierarchical Cellular Multihop Networks

Mobile communication systems beyond 3G will comprise cellular and self-organizing networks. In this paper an appropriate migration path towards the convergence of these two network types is highlighted and the resulting common radio network architecture is presented. By means of example scenarios the way to beneficially combine both network types will be described. Thereby, transport oriented a...
