Methods and systems for node selection in multihop wireless sensor networks

A system for transmitting data packets in a multihop wireless sensor network comprising a plurality of nodes, the system comprising:

• a database;
• and
• a processor, wherein the processor is operatively coupled to the database, the processor configured to:
• determine a leftover energy associated with each neighboring node of a source node;
• determine a secure value associated with each neighboring node of the source node;
• generate a potential candidate set comprising at least one node of the neighboring nodes associated with the source node, wherein leftover energy of each of the at least one node is greater than an energy threshold;
• generate an actual candidate set, wherein the actual candidate set comprises nodes from the potential candidate whose secure value is greater than a secure threshold;
• sort the actual candidate set based on a priority value, wherein the priority value is determined based on the secure value;
• and
• select a node with the highest priority value in the actual candidate set for transmission of a data packet from the source node.

A computer-usable medium having non-transitory computer readable instructions stored thereon for execution by a processor in a multihop wireless sensor network comprising a plurality of nodes to perform a method for:

• determining a leftover energy associated with each neighboring node of a source node;
• determining a secure value associated with each neighboring node of the source node;
• generating a potential candidate set comprising at least one node of the neighboring nodes associated with the source node, wherein leftover energy of each of the at least one node is greater than an energy threshold;
• generating an actual candidate set, wherein the actual candidate set comprises nodes from the potential candidate whose secure value is greater than a secure value threshold;
• sorting the actual candidate set based on a priority value, wherein the priority value is determined based on the secure value;
• and
• selecting a node with the highest priority value in the actual candidate set for transmission of a data packet from the source node.
