Aspects of the disclosure provide a method for selecting a relay node at a first node for transmitting a packet from the first node to a destination node in a wireless sensor network that includes a plurality of nodes. The method can include establishing a transmission angle within which the relay node is preferentially selected, wherein a bounding box surrounding the destination node is between a first side and a second side of the transmission angle, and selecting a second node having a highest remaining energy level among energy levels of neighbor nodes of the first node within the transmission angle to be the relay node. In one example, the candidate nodes for selecting the second node have a remaining energy level above a threshold.

Sensor node for selecting and transmitting a data packet to a relay node

Density-based method for selecting a relay node

Described herein is a method of deploying sensors by a robot in a geographical region. The robot receives a first instruction including information corresponding to the geographical region and a second instruction indicating one of a first manner and a second manner of deploying sensors. The robot computes a path to traverse the region in a plurality of steps, each step of the plurality of steps having a predetermined magnitude. The robot traverses until a stopping condition is satisfied. The robot deploys sensors at each traversed step size and further receives from each deployed sensor, information indicating absence of sensors in a neighboring area of the deployed sensor. Additionally, the robot repeats the traversing and deploying of sensors in the neighboring area to provide full coverage.

The method of routing for wireless ad hoc and sensor networks is a routing protocol that uses a greedy approach, selecting the best route having the maximum remaining energy above a pre-defined threshold limit. The method of routing for wireless ad hoc and sensor networks is an energy efficient routing protocol, in that the routing path is selected to maximize the lifetime of an individual source-destination pair by selecting a route between them that is based on the energy levels of neighboring nodes, without requiring an energy-intensive network flooding approach. The routing path between a source node and a destination node is selected by choosing, at each node, a neighboring node that has the greatest remaining energy level.
