Abstract

A common technique to detect this orger! node "eha#iour is net$or%

monitoring using &oca& $atchdogs.

A node's $atchdog consists on o#erhearing the pac%ets transmitted and

recei#ed "! its neigh"ours in order to detect anoma&ies( such as the ratio"et$een pac%ets recei#ed to pac%ets "eing retransmitted.

)! using this technique( the &oca& $atchdog can generate a positi#e *or

negati#e+ detection in case the node is acting orger! node *or not+.

As this techno&og! is app&ied monitoring and retransmit process

$ith paires o node

Objective

,he goa& is to o"tain the detection time *and o#erhead+ o a orger!

node in a net$or%.

,he main o"-ecti#e is to reduce the time and impro#e the

eecti#eness o detecting orger! nodes( reducing the harmu& eecto a&se positi#es( a&se negati#es and ma&icious nodes.

Existing system

n the /isting S!stem( it pro#ides t$o main strategies to dea& $ith

orger! "eha#iour

a+ moti#ation or incenti#e "ased approaches( and

"+ detection and ec&usion.

,he rst approach( tries to moti#ate nodes to acti#e&! participate in

the or$arding acti#ities.

,hese approaches are usua&&! "ased on #irtua& currenc! andor

game theor! mode&s.

,he detection and ec&usion approach is a straight or$ard $a! to

cope $ith orger! nodes and se#era& so&utions ha#e "een presented.


5/40

Disadvantage

,here is no orger! pre#ention mechanism is present.

,he pac%et de&i#er! rates "ecome serious&! degraded.

4e#erthe&ess( $atchdogs can ai& on this detection( generating a&se

positi#es and a&se negati#es that serious&! degrade the "eha#iour o

the s!stem.

,he pac%et is not retransmitted( thereore "eing &ost.


6/40

Proposed system

t com"ines &oca& $atchdog detections and the dissemination o this

inormation on the net$or%.

A node's $atchdog consists on o#erhearing the pac%ets transmitted and

recei#ed "! its neigh"ours in order to detect anoma&ies( such as the ratio"et$een pac%ets recei#ed to pac%ets "eing retransmitted.

t is "ased on the com"ination o a &oca& $atchdog and the diusion o

inormation $hen contacts "et$een pairs o nodes occurs.

A contact is dened as an opportunit! o transmission "et$een a pair o

nodes.


7/40

Advantages

t ta%es &ess detection time *and o#erhead+ o a orger! node in a

net$or%.

t reduce the time and impro#e the eecti#eness o detecting orger!

nodes( reducing the harmu& eect o a&se positi#es( a&se negati#esand ma&icious nodes.

t can reduce the o#era&& detection time $ith respect to the origina&

detection time $hen no co&&a"oration scheme is used( $ith a reducedo#erhead *message cost+.

A 4ono state means that it has no inormation a"out a node( a:ositi#e state means it "e&ie#es that a node is orger! node( and a

4egati#e state means it "e&ie#es that a node is not orger! node.

A node can ha#e direct inormation *rom the &oca& $atchdog+ andindirect inormation *rom neigh"our nodes+.
