Scheduling Beacon Transmission to Improve Delay for Receiver-initiated-MAC Based Wireless Sensor Networks

Altruistic Backoff: Collision Avoidance for Receiver-Initiated MAC Protocols for Wireless Sensor Networks

Receiver-Initiated vs. Short-Preamble Burst MAC Approaches for Multi-channel Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are networks formed by highly constrained devices that communicate measured environmental data using low-power wireless transmissions. The increase of spectrum utilization in non-licensed bands along with the reduced power used by these nodes is expected to cause high interference problems in WSNs. Therefore, the design of new dynamic spectrum access techniques s...

Receiver-initiated medium access control protocols for wireless sensor networks

One of the fundamental building blocks of a Wireless Sensor Network (WSN) is the Medium Access Control (MAC) protocol, that part of the system governing when and how two independent neighboring nodes activate their respective transceivers to directly interact. Historically, data exchange has always been initiated by the node willing to relay data, i.e. the sender. However, the ReceiverInitiated...

A Lightweight Intrusion Detection System Based on Specifications to Improve Security in Wireless Sensor Networks

Due to the prevalence of Wireless Sensor Networks (WSNs) in the many mission-critical applications such as military areas, security has been considered as one of the essential parameters in Quality of Service (QoS), and Intrusion Detection System (IDS) is considered as a fundamental requirement for security in these networks. This paper presents a lightweight Intrusion Detection System to prote...

SA-RI-MAC: Sender-Assisted Receiver-Initiated Asynchronous Duty Cycle MAC Protocol for Dynamic Traffic Loads in Wireless Sensor Networks

Duty cycling is an efficient mechanism to conserve energy in wireless sensor networks. Several existing duty cycling techniques have been proposed to conserve energy, but they are not able to handle the contention under dynamic traffic loads. In this paper we propose a protocol called Sender-Assisted-Receiver-Initiated MAC (SA-RI-MAC) which solves this problem without sacrificing the energy eff...
