“…A distinctive feature of Z-MAC is that its performance is robust to synchronization errors, slot assignment failures and time varying channel conditions; in the worst case, its performance always falls back to that of CSMA. Although Z-MAC has several merits, its overhead and complexity is quite high and its performance may not be better in a good channel condition or 2) Asynchronous MAC: Asynchronous MAC protocols [4]- [6] have no control overhead for synchronization unlike synchronous approaches so that the energy efficiency improves better than those approaches. Alternatively, the channel sampling, called low power listening (LPL) is utilized for data forwarding in asynchronous MAC protocols.…”

“…RI-MAC is suitable for random traffic (priority) applications. AS-MAC (ASynchronous-MAC) [6] employs the successive preloads approach by transmitting a series of preload packets, each containing the address of the target node, the duration of data transmission, and request sampling period RSP, instead of one long preamble. A series of preloads prevents non-target nodes from consuming energy for overhearing.…”

In this paper, we present research trends of communication protocols in wireless sensor networks (WSNs) focusing on application services' traffic condition features. We first outline the application services' traffic condition features and design challenges for communication protocols in WSNs. Focusing on these traffic condition features, synchronous and asynchronous MAC protocols, flat and hierarchical routing protocols, cross-layered protocols in WSNs are studied and their performances are evaluated. Finally, we highlight critical requirements for communication protocols design of WSNs considering these application services' traffic characteristics and discuss future research directions.

“…However, this scheme cannot guarantee multimedia traffic QoS, because the EDCF results in high collision rate at high multimedia traffic load. Most contention-based schemes [2,3] cannot guarantee multimedia traffic QoS due to collisions of control packets. The second is time division multiple access (TDMA) MAC protocols.…”

Wireless sensor networks (WSNs) are a vibrant research field for the last several years. Especially, design of MAC protocols supporting multimedia traffic QoS is recent challenging work. However, the mechanisms of protocols that can guarantee multimedia traffic QoS have several problems in multihop wireless sensor networks. There are a lot of reasons, including limited end-to-end delay and high throughput. In this paper, we propose ascalable MAC protocol that guarantees multimedia traffic, still images, and scalar sensor data QoS in multi-hop wireless sensor networks. The MAC protocol has made it possible to transmit multimedia streaming traffic without a great change of the end-to-end delay for a specific time. And if there are the some link failures in multi-hop transmission, the protocol can recover the links quickly. Using this algorithm, the proposed MAC protocol outperforms the IEEE 802.11e EDCF and the IEEE 802.15.4 MAC protocol in terms of the end-to-end delay and stable transmission of multimedia streaming data.
