“…In S-TDMA, if a node has no data to transmit, it will not have any time slot, thereby, decreasing latency. Simulation results in Boulfekhar et al (2012)indicate that S-TDMA outperforms LEACH protocol in terms of energy efficiency and latency and packet delivery ratio.…”

Wireless sensor network (WSN) is a network of a large number of battery-powered tiny sensor nodes wirelessly connected together to facilitate a wide range of monitoring applications. As WSN nodes are energy-constrained microelectronic devices, the primary design objective of WSNs is to minimise energy consumption to prolong the network lifetime. To achieve this goal, a range of cross-layer techniques, particularly focusing on medium access control (MAC) sublayer, is proposed targeting different WSN applications. This paper aims to survey low-power WSN MAC protocols, proposed from 2000 to the present, emphasising some general aspects including the issues addressed, the solutions proposed, design principles, strengths, drawbacks and target applications. With this aim, we mainly classify the MAC protocols into three categories: contention-based protocols, time division multiple access (TDMA)-based protocols and hybrid protocols, where the first category is further subdivided into subclasses. The development trends and potential research challenges are also discussed.

“…In Boulfekhar et al (2012), a TDMA-based energy-efficient MAC protocol named S-TDMA is proposed to maximise network lifetime by reducing major energy wastages such as idle listening, collisions and overhearing. Overhearing is avoided by letting nodes, which are not in the reception period, go to sleep mode.…”

A satellite is a way that allows a system administrator to receive data collected by sensors in different geographical areas. To realize this task, a medium access control (MAC) protocol in sensor networks must minimize power consumption in order to extend the lifetime of sensor nodes. To remedy this problem, we first assumed an architecture based on a Low Earth Orbit satellite and a network of heterogeneous sensors (Ordinary Nodes 'ONs' and Cluster Heads 'CHs'). We proposed a MAC protocol, called Satellite Sensor MAC (SS-MAC), which avoids the different causes of energy dissipations. The basic idea behind our protocol is to minimize the number of communications. This number is based on the data quantities collected by each ON (or each CH) in order to extend the lifetime of ONs, which means extend the network lifetime. Our protocol uses four periods: a period for the grouping nodes to form clusters, a Transmission/ Reception period between ONs and their CHs, a period when the satellite allocates slots to CHs and a period when CHs send their data to the satellite. Finally, the energy consumption in each period was evaluated through its protocol analysis, numerical results and Markov chain models. All these results have shown the energy-efficient of the SS-MAC protocol.

The widespread use of mobile devices in digital community has promoted the variety of data collecting methods. However, the privacy of individuals plays an important role in data processing or data transmission, and such information should be protected. In this paper, (α, k)-anonymity model, a widely used privacy-preserving model, is adopted as a security frame. Then, a privacy-preserving data collection model ((α, k))-CM based on (α, k)-anonymity is proposed and the threat model is analyzed. To resist the possible attack, we propose a generalization-encryption method to achieve a desired privacy level in (α, k)-CM. Generalization can decrease the data size and save the resource might induce information loss in data process; while encryption can decrease information loss, however, it can cause the waste of resource. Generalization-encryption method dynamically encrypts a portion of the data with maximum information loss and adjusts the portion to balance the trade-off metric in the process of generalization. Experimental results and theoretical analysis show that this method is effective in terms of privacy levels and data quality with low resource consumption.
