Novel Hybrid Orthogonal Large Set Code Sequence for High Density Wireless Networks

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...

Orthogonal Code Based Anonymity Communication Protocol for Wireless Sensor Networks

In some environments, the security of the wireless sensor networks (WSNs) involves not only the security of sending data, but also the anonymity and privacy during data delivery, how to design a secure efficient anonymity communication scheme for wireless sensor networks has became an important research topic. The proposed schemes can provide efficient anonymous communication, but some of the s...

On Large Throughputs in High Density Wireless Local Area Networks

While the density of access points in enterprise settings has increased, the sharing of the spatial resource amongst links in 802.11 wireless local area networks remains inefficient. Conservative mechanisms based on a static carrier sense range (CSR) are used and are designed to avoid occurrence of interfering transmissions. Even when the CSR is adapted to allow interfering transmissions, it is...

Large-Scale Programing Code Dissemination for Software-Defined Wireless Networks

A Novel Joint Spatial-Code Clustered Interference Alignment Scheme for Large-Scale Wireless Sensor Networks

Interference alignment (IA) has been put forward as a promising technique which can mitigate interference and effectively increase the throughput of wireless sensor networks (WSNs). However, the number of users is strictly restricted by the IA feasibility condition, and the interference leakage will become so strong that the quality of service will degrade significantly when there are more user...
