CHOOSING THE BEST ROUTING PROTOCOL FOR WIRELESS SENSOR NETWORKS
Due to the rapid development of wireless technologies, the optimal choice of network types and routing protocols is an urgent task. The current state of traffic models in terms of routing protocols in wireless sensor networks (WSN) is considered. The class of corresponding low-power network (LLN) provides efficient routing when transmitting data packets in small local networks. The AODV (Ad Hoc On-Demand Distance Vector) dynamic routing protocol in the BSS minimizes the length of the traffic route. Modeling traffic in the FSU is considered using color images as an example. For aggregated heterogeneous traffic flows in the network, the Kolmogorov criterion is applied, and dependences are obtained that allow one to calculate the Hurst coefficient using analysis of the variant variable . The same parameter is calculated as optimal for a packet of images on a sensor field of depending on the number of transmitting nodes and is equal to . For the WSN, various connection options with various connection options for the client and operator in the presence or absence of a base station are considered. Also, for wireless sensor networks, the RPL and AODV protocols are compared by simulation. Shown, the first is optimal. From the perspective of the 5th generation networks, it is possible to use D2D (device-to-device) connections. In this version of the two protocols (AODV, DSDV), AODV is more preferable both for the minimum total delay time and the minimum number of steps in data transfer. The development of 5th generation wireless networks will bring traffic to the level of broadband wired Internet and provide a qualitatively new level of opportunities for customers of these networks.
