Abstract
A network of environmental sensor nodes is proposed in which data is transmitted wirelessly between the nodes using a rateless erasure code with a redundancy which is matched to the effective data rate, thereby permitting distanceless link transmissions. The wireless sensor networks is suitable to be sparsely deployed over wide area. A communication protocol is proposed to efficiently coordinate the distanceless link transmissions. A new metric (expected distanceless transmission time) is proposed for routing selection. The distanceless transmissions are well-adapted to low duty-cycled sensor networks.
