“…Campbell et al [8], [9] studied multichannel communication based on the 802.11 DCF over a single radio for Wireless Sensor Networks in order to improve its communication performance on throughput, end-to-end delay and channel access delay. They proposed back off algorithm (MC-DCF), which allows nodes to have access to multiple non-overlapping channels by accessing channels dynamically through channel switching after a set threshold has been met.…”

Internet of Things (IoT) presents a promising technology concept for a wide range of applications due to the possibility of interconnecting any device with connection to Internet in order to improve the daily life of human beings. This fact, along with the increasing use of devices with wireless capabilities has created a saturation problem in the use of the radio-electric spectrum, which decreases the performance of wireless communications. A way to solve this problem is to develop policies for communicating nodes in different spectrum channels by means of the use of a dual radio scheme, which permits the communication in the same network using several channels. In this paper, we evaluate the performance of a dualradio scheme in IEEE 802.15.4 networks for the Ad-Hoc Ondemand Distance Vector routing protocol (AODV). The evaluation of our proposal has been done by developing a new IEEE 802.15.4 dual-radio module for OMNeT++ Network Simulator. Our simulation results show up to 36 % increase of network throughput when dual-radio schemes are used in the nodes, reaching a maximum of 20 % increase in the energy consumption.

“…We analyze the performance of our scheme via simulations, under realistic wireless scenarios. In our previous work [ 7 , 8 ] the single radio switches nodes to receive data from other sending nodes on different channels. The results obtained at the sink from the sending nodes have shown that MC-DCF performs very poorly.…”

“…We will increase the number of sink nodes to collect data from receiving nodes. The sink nodes will be equipped with a single radio and will be required to do channel switching in the same manner as in [ 7 , 8 ]. The advantage is that all data from senders will be received by more sink nodes located in strategic positions.…”

The next generation surveillance and multimedia systems will become increasingly deployed as wireless sensor networks in order to monitor parks, public places and for business usage. The convergence of data and telecommunication over IP-based networks has paved the way for wireless networks. Functions are becoming more intertwined by the compelling force of innovation and technology. For example, many closed-circuit TV premises surveillance systems now rely on transmitting their images and data over IP networks instead of standalone video circuits. These systems will increase their reliability in the future on wireless networks and on IEEE 802.11 networks. However, due to limited non-overlapping channels, delay, and congestion there will be problems at sink nodes. In this paper we provide necessary conditions to verify the feasibility of round robin technique in these networks at the sink nodes by using a technique to regulate multi-radio multichannel assignment. We demonstrate through simulations that dynamic channel assignment scheme using multi-radio, and multichannel configuration at a single sink node can perform close to optimal on the average while multiple sink node assignment also performs well. The methods proposed in this paper can be a valuable tool for network designers in planning network deployment and for optimizing different performance objectives.
