Title: "Channel Assignment in Wireless Sensor Networks"

Miss Yanyan Yang


Abstract:

Wireless sensor networks (WSNs) are featured with low-cost, low-power and
multi-functionality, which make WSN-based applications with large scale
and dense deployments possible. While traditional ways are to use a single
channel among the whole WSN, they cannot work well when the WSN grows
larger and denser in that frequent interference and collisions among the
WSN decrease the throughput dramatically. To provide higher throughput and
to achieve better energy efficiency, how to use the available multiple
channels effectively becomes a very attractive issue. In this survey
paper, we will firstly list the unique features and challenging
requirements for WSNs. Secondly, we will introduce our comprehensive
studies on multi-channel availabilities of the sensor nodes. Then we will
categorize the current protocols into five classes according to their
objectives: interference-free; throughput improvement; data dissemination;
application-oriented and co-existence of WSNs and other wireless networks.
We will also make a comparative study of these protocols. Finally, we will
summarize the paper along with some discussions about possible research
issues in the future.
