Analysis of tengda multi-hop Network Routing Protocol

Tengda multi-hop network routing protocol analysis what we call multi-hop Network is an dynamic topology, that is, WMN, which is derived from the Ad hoc network, it can be divided into geo-assisted routes and non-geo-assisted routes. 1. In WMN, The TBRPF-based routing protocol, the DSR-based routing protocol, the DSDV-based routing protocol, the difference between WMN and Ad hoc is that the application of Ad hoc network routing protocols in WMN cannot optimize the performance of WMN. Www.2cto.com II. main considerations: 1. Cross-layer protocol design combined with the physical layer of the direction antenna, multi-input and multi-output and link layer technologies, protocols at different layers are collaborative and integrated design. 2. Fault tolerance when the Mesh client is moving, the wireless link is congested, or the Mesh router is faulty, the routing can be reselected. 3. The number of WMN networks supported by the network is generally large, and the routing protocol must support more nodes. If you directly use the traditional Ad hoc network routing protocol, the routing search process may take too long and costly.
4. The link interferes with the wireless signals sent from neighboring nodes. When selecting a route, select a link with a small amount of interference to increase the system capacity. 5. route selection is based on the number of hops www.2cto.com (1): The number of wireless links passing through the path between the source node and the target node. (2) expected number of transmissions (ETX): The number of retransmissions due to media access conflicts. It is a common parameter in wireless communication. (3) expected transmission time (ETT): it is more commonly used than ETX. It also takes into account the bandwidth characteristics of the channel. (4) round-trip transmission time (RTT): the time required for back-trip transmission between the source and destination nodes of the group. (5) Energy Consumption: the total energy consumption caused by a certain transmission route. (6) Route stability: This article describes how stable a route is and how long it can last. Mesh routers are equipped with more than two Wireless Transceiver Devices in the application of network convergence. The design of the routing protocol needs to consider the characteristics of Multi-wireless transceiver and multi-channel. In wireless access applications, generally, the WMN network performance can be improved only when the characteristics of the WMN network structure and application characteristics are taken into consideration based on the wireless self-organizing network technology.
