METHOD FOR DISTRIBUTED TRAFFIC BALANCING IN WIRELESS SENSOR NETWORK Russian patent published in 2014 - IPC H04W40/04 H04W72/12 

FIELD: radio engineering, communication.

SUBSTANCE: invention discloses a method and a system for distributed traffic balancing in a wireless sensor network based on an algorithm for routing from a source node to a destination node, where the wireless sensor network is presented as a graph G (N, M), where N denotes network nodes and M boundaries. There are K routes and information is generated at a rate Q_c and transmitted over a communication channel C at a rate q_c. The i-th node has an energy margin E_i, and each boundary ij has a weight/value e_ij which corresponds to energy for transmitting one data packet from node i to j, and the life T_i of each node is defined as . Each node determines a routing table and stores a message transmission vector, performs analysis of routing alternatives on the most optimum sum vectors calculated from the routing table. To this end, the life of the entire network $${\text{T}}_{\text{sys}}=\underset{i\in N}{{\displaystyle \min }}{\text{ T}}_{\text{i}}(q_c)$$ is determined. Maximisation of the life is defined as maximise T_sys, and to achieve maximum life of the entire network, routes are distributed, where the choice of a route in a network is based on use of the least costly transmissions at each node and the most costly transmissions are excluded.

EFFECT: providing efficient routing, prolonging the life of a network and high reliability.
