Interaction of communication within adjacent channels in sensor wireless network

This paper presents experimental measurements of communication interaction within the adjacent channels in a sensor wireless network. The sensor wireless network operates in 868 MHz frequency band with 200 kHz logical channel spacing and is intended for ad-hoc distance vector routing protocol operating within one logical channel. Packet loss within such network influences performance of routing protocol. The measurement was carried out to obtain a useful information about the packet loss in the sensor network caused by simultaneous communication on one of the adjacent channels. The packet loss caused by simultaneous communication on 1^st, 2^nd, 3^rd and 4^th adjacent channel was determined.
