Routing Issues in Wireless Sensor Networks: A Survey (original) (raw)

2013, International Journal of Advanced Research in Computer Science and Software Engineering

Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing, power management and data dissemination protocols have been specifically designed for WSNs where energy awareness is an essential design issue. The focus, however, has been given to the routing protocols which might differ depending on the application and network architecture. In this paper, we present a survey of the routing protocols in WSNs. The routing techniques are classified into three categories based on the underlying network structure: flat, hierarchical and location-based routing. Furthermore, these protocols can be classified into multi path-based, query-based, negotiation-based, QoS-based, and coherent based depending on the protocol operation. In this proposed work, the advantages and performance issues of each routing protocols are also highlighted.
