Problems solved by technology

However, when data is transmitted within the same area, it may cause a node to die due to excessive energy consumption for frequent forwarding tasks. In addition, all nodes in the network are always in a working state regardless of whether they have forwarding tasks. , also increases the network energy consumption
[0012] After the above analysis, there is still the problem of too fast energy consumption of network nodes in related research work, so we propose the Energy Efficient Opportunistic Routing Protocol EEORP

Embodiment Construction

[0083] 1. Network model and EEORP protocol

[0084] 1.1 Network Model

[0085] Assume that a WSN with multiple nodes and a unique sink node is deployed in the monitoring area of ​​a two-dimensional plane. The initial energy of all nodes in the network is the same, and the energy of sink nodes is infinite. Under the requirements of event monitoring in the monitoring area, each node can collect data and relay and forward data packets, and there are enough neighbor nodes for relay node selection. Each node knows its own geographical location information, and knows the geographical location information of the sink node and the Euclidean distance from itself to the sink node, and has certain computing power.

[0086] Nodes use a periodic sleep and wake-up mechanism in network work. In order to ensure that nodes in the network can sense, collect, and transmit data in a timely manner when events occur in the monitoring area, it is required that nodes in the network cannot be in a s...

Abstract

The invention relates to a wireless sensor network energy effective opportunistic routing protocol implementation method. According to the method, a first relay node and a standby relay node are selected in a data transmission process; and the standby relay node is utilized to realize collaborative data forwarding; and therefore, the reliability and timeliness of data forwarding can be improved.

Description

technical field [0001] The invention relates to wireless sensors, specifically, aiming at the problems of limited energy of nodes and untimely data transmission of wireless links in opportunistic routing of wireless sensor networks, the paper proposes an energy efficient opportunistic routing protocol implementation method. Background technique [0002] Wireless sensor network (WSN, wireless sensor networks) is a wireless multi-hop network formed by nodes deployed in the monitoring area capable of information collection, data processing and wireless communication. Compared with the traditional wireless multi-hop network, WSN cooperatively perceives, collects and processes the perceived object information in the monitoring area, so that observers can obtain event information in a timely manner. Therefore, WSN is widely used in military monitoring, temperature monitoring, wild animal tracking and early warning mechanisms, etc. Nodes in the monitoring area are usually powered ...
