SISP: A lightweight synchronization protocol for Wireless Sensor Networks

Abstract

This paper presents a new synchronization protocol suitable for light nodes in a Wireless Sensor Network. This protocol, called SISP, is detailed with its algorithm and its sequence diagram. The simulation results obtained with a dedicated simulator are completed by the results of prototyping. The results show the effectiveness of SISP. Several prospects are discussed in conclusion.

Towards a new range-based localization method for WSNs: Challenges, Constraints and Correction

“…In the case of mesh networks, with reasonable density, a mobile may establish a connection to any reachable reference node. Unfortunately this structure does not naturally support network wide synchronization without some specific algorithm such as [4]. On the other hand, a tree-topology will provide a backbone along which to share that synchronization but will restrain the possible connections.…”

“…If the focus switches to energy saving, a tree topology becomes the ideal case as its structure eases the establishment of a common schedule throughout the network: energy waste can thus be limited by entering sleep mode on regular intervals. Other topologies can also be used but would require a synchronization protocol such as SISP [4] which does not depend on the network structure. The work in [5] also addressed the problem from the energy angle.…”

“…In order for the nodes to be able to shut down their radio interface without losing frames, a synchronization is necessary. Depending on the requirements of upper layers, this task can be accomplished using a mechanism such as [4].…”

Distributed Physical-layer Network Coding MAC protocol

“…• Reliable coordination: Involved nodes in the TWRC scenario could carry their clock information in the control frames (RTS, CTS, ...) to coordinate the channel access between them and guarantee a simultaneous data transmission when performing PNC. The initial synchronization of the clocks of the nodes can be inspired from [30], [17], [19], [18], [4], [20], [9], and [21].…”

“…. Nous ne détaillons pas le mécanisme de synchronisation utilisé, qui peut s'appuyer sur plusieurs protocoles existants, comme RBS[EGE02], TPSN[GKS03], l'intervalle [T 0 ; T 1 ] de Macari, ADCF[LvdBC11] ou SISP[vdBVD11].…”
