\begin{abstract}
Wireless sensor networks (WSNs) enable new applications and require non-conventional paradigms for protocol design. Owing to the requirements for self-organization, scalability and primarily low energy consumption needs, a proper balance between communication and data processing capabilities must be maintained. This motivates a huge effort in research activities and investments on this field for past few years. At present most of the research on WSNs has concentrated on the design of energy and computationally efficient algorithms and routing protocols with application domain restricted to simple data-oriented monitoring. In this paper, we presented a comprehensive analysis on WSNs routing with key challenges for development of protocol designs. At last we discussed some open issues for future directions in WSNs for research contributions.

\section{Introduction}
Wireless Sensor Networks (WSNs) contain self-configured, distributed, autonomous and resource empowered sensor nodes that monitor physical or environmental activities, such as humidity, temperature, sound, vibration or pollutants in a specific area of operation\cite{akkaya2005survey}. Sensor nodes \cite{abbasi2007survey}cooperatively \cite{al2004routing}pass their sensed data through the wireless\cite{bi2010ant} network to a main location, known as sink or base station where the data can be monitored and analyzsed for decision making.

Ref.bibormodel1-num-names.bstYou should supply a short sample .bib file and perhaps a link tomodel1-num-names.bst. It is also unclear what the sentence "the cross reference is not referring to bibliography" means. Describe what happens and how it differs from what you want. – Dan Nov 22 '13 at 04:24model1-num-names.bst. – Dan Nov 22 '13 at 21:12\usepackage{hyperref}.
