| description | Topology control in wireless sensor networks tries to improve the performance by reducing transmission power and by confining interference, collisions and consequently retransmissions. Network performance is assessed using LQI, RSSI, BER etc. LQI a metric introduced in IEEE802.15.4 that measure the error in incoming modulation of successfully received packets [1]. In this paper, we analyze popular topology control algorithms w.r.t weak link BER and propose a novel technique to optimize BER with additional relay nodes. We introduce additional relay nodes to make the network connected instead of increasing the power. Thus it also results in saving energy. We have also evaluated the algorithm combining with LIFE, GG and RNG algorithms and demonstrated its superiority in giving high quality network. |
