Abstract
To explore the algorithms for wireless self-organized networks, through the NS-2 network simulation platform, the simulation analysis is made on the performances of multi hop data transmission of the existing four typical Ad hoc network routing protocols. And the energy saving strategy of Ad hoc network routing protocol SFR (Selection Forwarding Routing) based on network average node connection degree is discussed and analyzed, which is suitable for intensive Ad hoc network. The simulation data showed that, SFR protocol can, under the premise of ensuring the network coverage rate the same as that of flooding algorithm, reduce more than 56.1% redundant information in the network, and reduce the energy consumption of network by more than 30.2%. Finally, it is concluded that the selection forwarding routing has quite good performance.
Highlights
The energy saving strategy of routing protocols in Ad hoc network, in the NS-2 network simulation platform, the simulation analysis is made for on-demand routing protocols AODV and DSR, table driven routing protocol DSDV and temporary sequence routing protocol TORA based on the "height" concept
Based on the analysis of four typical Ad hoc network routing protocol and typical Flooding broadcast protocol, the routing protocol Selection Forwarding Routing is proposed based on the network average node network connectivity, which is suitable for intensive Ad hoc network
We mainly focus on vertical comparison of three indicators, the AODV end-to-end delivery rate, end-to-end delay and energy consumption ec
Summary
The energy saving strategy of routing protocols in Ad hoc network, in the NS-2 network simulation platform, the simulation analysis is made for on-demand routing protocols AODV and DSR, table driven routing protocol DSDV and temporary sequence routing protocol TORA based on the "height" concept. In the energy consumption analysis, a completely new evaluation method Bec of energy consumption byte level that can accurately measure multi hop data transmission energy consumption is put forward This method is used to make indepth analysis and comparison of energy consumption of four routing protocols. Based on the analysis of four typical Ad hoc network routing protocol and typical Flooding broadcast protocol, the routing protocol Selection Forwarding Routing is proposed based on the network average node network connectivity, which is suitable for intensive Ad hoc network In this protocol, unlike the traditional routing protocols, it is no longer that all the nodes are forwarding routing look-up messages, but only a few nodes that meet the connectivity conditions continue to forward the routing lookup message. This paper uses the simulation platform to study the energy saving performance of routing protocols in Ad hoc networks, and analyzes the situations of reducing routing energy consumption
