Abstract
• The development of micro-electronics technology, computing
technology and the wireless communications technology, wireless
sensor networks (WSNs) has been great concerned in recent years.
• The architecture of WSN directly affect entire network performance,
and the network performance affects the availability of WSN.
• The design of WSN architecture need consider many aspects, such as
deploy, energy consumption, expansibility, flexibility and error
tolerance.
• The cross-layer MAC protocol can be designed to reduce energy
consumption and prolong the network lifetime.

2 micro electronics technology
3 wireless communication technology
4 embedded computing and distributed processing technology
WSNs is composed by a large amount of micro sensor nodes
distributed in monitored area
purpose of building WSN
• to collaboratively sense
• collect and process the information of the objects detected in the
monitored area and
• then sends it to the observer [2].

Methodology
Data collection Methodology
1 Data collection methodology:literature,discussion,Related works.
Design approach
• Cross-layer design: WSNs has a layered structure, so it is designed
according to layered idea..
• The goal of cross-layer design is to achieve design performance
balance between nonadjacent protocol layer logically.
• Fusion with other networks: fusion of WSNs with existing networks
will bring new applications.

CROSS-LAYER MAC PROTOCOL OF WSNS
• In data receiving and dispatching, the sensor nodes have four states:
1 dormancy
2 monitoring
3 receiving and sending
4 the energy consumption of sending and receiving is maximum.
• In design of communication protocol, as an important infrastructure
of WSNs stacks.
• the MAC protocol determines the use-pattern of wireless channel,
allots wireless communication resource for sensor nodes, directly
influences the overall network performance, and becomes top priority
of WSNs research.

Gaps on the Reviews
• This paper lack of methodology
• No mathematical method and result were included.
• the critical outline of the paper is little bit far apart from the truth
although new paper were done in this area.

are introduced. At last, the conclusion and future work of WSNs is
discussed

Conclusion and future works
Conclusion
• WSNs have a very wide range of applications.
• With the gradual resolution of a series of key technologies, WSNs will
be a very large all-pervasive network in the future.
• According to the characteristics of WSNs, the major challenges in the
future appear in five aspects that include
1 lower energy consumption
2 real-time
3 low cost
4 security
5 anti-jamming and cooperation.
• The design of every layer is mutually independent, so it is limited,
then the optimization design of every layer could not guarantee
optimal design of the entire network.
