Abstract
This research exploits the new concept of route discovery using TCNet - Trellis Coded Networks an algorithm and routing protocol based on convolutional codes to be used in WSNs an important infrastructure of the Internet of Things (IoT) architecture. This work shows the robustness of the TCNet algorithm in making decisions in cases of nodes failure and packages collisions, taking advantage of the regeneration capacity of the trellis. This proposal innovates in making decisions on the node itself, without the need of signaling messages such as “Route Request”, “Route Reply” or the RTS and CTS. TCNet uses low complexity Finite State Machine (FSM) network nodes (“XOR” gates and shift registers), eliminating the use of any routing tables by means of Trellis decoding, where the sequence of states of the FSM, corresponds to a network route, and can be chosen based on different optimization criteria.
