abstract = {To provide for reliability in Wireless Sensor Networks (WSNs), Medium Access Control (MAC) protocols must
be adapted by mechanisms taking cross-layer approaches into
account. We describe AreaCast which is designed for enhancing
reliability in WSNs. AreaCast is a MAC layer mechanism independent of the routing layer, but uses only local topological and
routing information to provide a communication by area instead
of a traditional, node-to-node communication (i.e., unicast). In
AreaCast, a source node addresses a set of nodes: an explicit
relay node chosen as the next hop by a given routing protocol,
and k other implicit relay nodes. The neighboring nodes select
themselves as implicit relays according to their location from
the explicit relay node. This mechanism uses overhearing to take
advantage of the inherent broadcast nature of wireless commu-
nications. Without changing the routing protocol, AreaCast is
able to dynamically avoid a byzantine node or an unstable link,
allowing to benefit from the inherent topological redundancy of
densely deployed sensor networks. Simulation results show that
AreaCast significantly improves the packet delivery rate while
having a good reliability-energy consumption trade-off.
