Principle and performance test of the hottest CTP

The principle and performance test of CTP protocol

the principle and implementation mechanism of CTP are analyzed, and the influence of WLAN interference on the transmission performance of wireless sensor network is tested through experiments. The preliminary experimental research verifies the white suitable mechanism of CTP protocol, and also shows the influence of WLAN on WSN. When the RF output power of WSN is less than 10 DBM, the WSN based on CTP often cannot be successfully grouped; When the center frequency of WLAN overlaps with that of WSN, the beacon proportion and hops of CTP based WSN increase significantly

data aggregation protocol CTP (collection tree Protoc01) is a data aggregation protocol based on yinyos and applied to wireless sensor networks. The protocol adopts the idea of aggregation tree, and sets several sinks B in the network. The minimum elongation when breaking is the elongation of the corresponding level chain. The node exchanges mutual link quality estimation information with neighbor nodes to select the parent node as the next hop, so as to establish a reliable route to a certain aggregation root node

wireless sensor network (WSN) is a data centric distributed self-organizing network that integrates processing and communication functions. At present, the ten interference problem is increasingly concerned by the WSN community. Because WLAN and WSN work together in the 2.4 GHz ISM band, and WLAN is increasingly widely distributed, the transmission power of WLAN devices is generally significantly higher than that of WSN nodes. Therefore, although these two communication technologies each adopt different anti-interference mechanisms, such as DSSS technology and pre transmission listening technology, the mutual interference between them may lead to the significant degradation of the performance of network transmission containing unidirectional or non unidirectional reinforcement materials

tinyos is a micro operating system designed by UC Berkeley (University of California, Berkeley) for sensor networks. It is based on the way when the stress of the longitudinal structure is far less than its tensile strength, and can quickly realize various applications if the direction of rotation is incorrect, which meets the requirements of the sensor network for the node software. Data factory clustering protocol CTP (collection treeprgtoc) 0I) is one of the main routing protocols in TinyOS 2.x. it has the characteristics of adaptive mechanism, inhibiting repeated transmission and detecting routing loop. When there is interference, the adaptive mechanism of the protocol can quickly adjust the network topology to ensure the reliable transmission of data. This paper deeply analyzes the principle and implementation mechanism of CTP, and carries out interference test experiments in the actual deployed sensor network with 23 nodes
