as shown in Figure 10 even in the course of mobility due to the periodic update
of multi-hop paths. The total network energy consumed during the lifetime of the
SANETs is considerably low with ADP compared to previous proposed coordination
protocols.
4 Conclusion and Future Work
For sensor-actuator coordination, the proposed ADP can acquire a promised QoS
for time stringent traffic at the cost of optimal energy consumption. For actuatoractuator
coordination, the proposed unified framework using AODV can be exploited
by different applications to always select the best networking paradigm
that is possibly available according to the sensed information and to perform the
necessary operations in an efficient way. The issues related to node-failures and
mobility are well handled by the periodic exchange of ’Hello’ messages in all deployment
scenarios. The energy consumption for obtaining new paths in-case of
failure is also energy efficient and is driven by the collaborative nature of SANETs.
For the moment, we are working on the design of a delay-energy sensitive
routing protocol to work in collaboration with our ADP, to make the architectural
and coordination platform sound for the future of SANETs. We are also working
on MAC optimization based on the proposal for the efficient utilization of sensorenergy
and to satiate the real-time problems experienced so far in the SANETs.
