Increasing computing and wireless communication capabilities will expand the role of the sensors from mere information dissemination to more demanding tasks as sensor fusion, classification, collaborative target tracking. This paper current provides comprehensive investigation of different routing schemes used in wireless sensor networks.
routing protocols may be classified in to one of the ensuing three models :
a. single hop model
b. multi-hop model
c. cluster-based hierarchical model.
single hop is the simplest model to reach a base station or the sink node. however, This kind of single hop transmission is highly unrealistic in the real world.
The multi-model supports the collaborative effort of several nodes within the sensor cloud. each sensor node has a radio range, which is referred to as the distance which the signal strength remains above the minimum usable level for that particular node to transmit and receive.

In the cluster based model, the network is divided into clusters comprising of number amount of nodes. Cluster head, which is master node, within each respective cluster is responsible for routing the information to other cluster head.

Protocol Assessment :
Some of the parameters used to evaluate the routing performance are :
a. Energy consumption, both with respect to an individual node and the whole network
b. Simulation time and latency
c. Success rate of the data packets reaching the sink
d. Network size
e. Fault tolerance capability of the entire network
Routing Methodology in WSNs :
Broad classification of routing methodology is on the basis of
a. Network structure
b. Protocol operation
Classification of routing protocols :
Flat Routing :
in Flat network architecture all the sensor nodes are equal and connections between nodes are set in short distance to establish the radio communication. Route discovery can be carried out in sensor networks using flooding or broadcasting which do not involve topology maintenance.
In this paper, the authors provide investigation some methods related to flat routing, that are :
– SPIN – Sensor Protocols for information via negotiation
– Directed Diffusion
– Rumor routing
Let see original paper for more detail 🙂
