Genetical Swarm Optimization of Multihop Routes in Wireless Sensor Networks

Abstract: In recent years, wireless sensor networks have been attracting considerable research attention for a wide range of applications, but they still present significant network communication challenges, involving essentially the use of large numbers of resource-constrained nodes operating unattended and exposed to potential local failures. In order to maximize the network lifespan, in this paper, genetical swarm optimization (GSO) is applied, a class of hybrid evolutionary techniques developed in order to exploit i… Show more

“…For each sender, an optimal route is defined by a single run of GSO and the network status and power level of each node are updated consequently. The best route is chosen by GSO according to fitness function which implements the set of rules presented in Section 5 and in [4]. Figure 3 shows the connectivity of the network and the energy-efficient distributed clustering scheme proposed by the optimization algorithm.…”

“…According to [4] a simple radio model has been used in this work, where the radio dissipates E el = 50 nJ/bit to run both the transmitter and receiver circuitry, and E amp = 100 pJ bit·m 2 for transmit amplifier to achieve an acceptable signal to noise ratio. An r 2 energy path loss due to channel transmission is also assumed and thus to transmit a k-bit message to a distance d using this model, the single sensor node expends:…”
