DELAY-DRIVEN ROUTING FOR LOW-DUTY-CYCLE SENSOR NETWORKS

Delay-Driven Routing for Low-Duty-Cycle Sensor Networks

Duty-cycled operation has been introduced as an efficient way to preserve nodes energy and prolong network lifetime for wireless sensor networks.However, such networks are often logically disconnected since there is a limited number of active nodes within a period of time.Traditional routing algorithms, which have been designed for always-awake wir
